Algebra and Function Practice
A blank slope graph is a coordinate grid paired with a dedicated side column for recording rise and run steps plus a y-intercept marker space. It supports plotting a line from an equation or two points by making the slope calculation visible before drawing. This lesson explains how to lay out and use such a template, how to record slope steps consistently, and how to check plotted lines. The template is a planned printable resource, not a finished file; the instructional copy below is complete and self-contained.

Template layout and conventions
Use a large square coordinate grid with equal spacing on both axes. Label the origin and mark axes with consistent unit intervals. Reserve a side column divided into three stacked boxes: a rise box, a run box, and a y-intercept marker space. The rise box records vertical change with a sign; the run box records horizontal change with a sign; the y-intercept space records the starting point as an ordered pair.
Define one convention explicitly before plotting: count rise upward as positive and downward as negative; count run rightward as positive and leftward as negative. Write slope as rise over run in the side column, then transfer the steps to the grid. Letter styles and handwriting vary, so accept any legible notation that preserves sign and order, such as arrows, plus and minus signs, or words like up and left.
- Draw or print the grid with equal unit spacing and label the axes.
- Divide the side column into rise, run, and y-intercept boxes.
- State the sign convention for rise and run at the top of the column.
- Record the y-intercept as an ordered pair before plotting any steps.
Plotting a line from slope and y-intercept
Start at the y-intercept recorded in the marker space. Apply the rise first, moving vertically the number of units in the rise box, then apply the run horizontally the number of units in the run box. Mark the new point clearly. Repeat the same rise and run from the new point to place a third point, then connect the points with a straight line.
Keep units consistent: one grid square equals one unit unless the axes state otherwise. If the slope is a fraction, the numerator is the rise and the denominator is the run. If the slope is negative, attach the negative sign to either the rise or the run, but not both, and record that choice in the side column so the plotted direction is checkable.
- Place the first point at the recorded y-intercept.
- Move vertically by the rise value and mark the temporary position.
- Move horizontally by the run value and mark the second point.
- Repeat from the second point to place a third point.
- Connect the points and label the line.
Checking plotted lines and slope records
Check that the vertical change between any two plotted points equals the recorded rise and the horizontal change equals the recorded run. Recompute slope as change in y divided by change in x and compare it with the rise over run written in the side column. Confirm the line crosses the y-axis at the recorded intercept.
A valid alternative is to record the negative sign on the run instead of the rise; the plotted direction must still match the recorded signs. Accept any legible side-column entry that states rise, run, and intercept unambiguously. If a plotted point does not align with the grid intersections, recheck the counting rather than adjusting the grid.
- Subtract y-values of two plotted points and compare with the rise.
- Subtract x-values of the same points and compare with the run.
- Divide the y-change by the x-change and compare with the recorded slope.
- Verify the y-intercept against the marker space entry.
Worked example
A line has y-intercept (0, 2) and slope 3/2. Using the template convention, record rise and run, plot three points, and state the slope check.
Worked answer
Record intercept (0, 2), rise 3, run 2. Plot (0, 2), then move up 3 and right 2 to (2, 5), then repeat to (4, 8). The y-change from (0, 2) to (2, 5) is 3 and the x-change is 2, so slope is 3/2, matching the record.
Four practice exercises
Exercise 1
A line has y-intercept (0, 1) and slope 2/3. Record rise and run, plot three points, and state the slope check.
Show answer and check
Rise 2, run 3; points (0, 1), (3, 3), (6, 5); slope check gives 2/3.
Why: Start at (0, 1). Move up 2 and right 3 to (3, 3), then repeat to (6, 5). The y-change from (0, 1) to (3, 3) is 2 and the x-change is 3, so slope is 2/3.
Check: Subtract coordinates of two plotted points: (3 minus 0) equals 3 for run and (3 minus 1) equals 2 for rise; divide 2 by 3 and compare with the recorded slope.
Exercise 2
A line has y-intercept (0, 4) and slope negative 1/2. Choose to place the negative sign on the rise, record the boxes, plot three points, and state the slope check.
Show answer and check
Rise negative 1, run 2; points (0, 4), (2, 3), (4, 2); slope check gives negative 1/2.
Why: Start at (0, 4). Move down 1 and right 2 to (2, 3), then repeat to (4, 2). The y-change from (0, 4) to (2, 3) is negative 1 and the x-change is 2, so slope is negative 1/2.
Check: Compute change in y as 3 minus 4 equals negative 1 and change in x as 2 minus 0 equals 2; divide to get negative 1/2 and compare with the side-column record.
Exercise 3
A line passes through (1, 2) and (4, 8). Record rise and run from these points, plot a third point using the same steps, and state the slope check.
Show answer and check
Rise 6, run 3, slope 2; third point (7, 14); slope check gives 2.
Why: From (1, 2) to (4, 8), the y-change is 6 and the x-change is 3, so slope is 6/3 equals 2. Repeating rise 6 and run 3 from (4, 8) gives (7, 14).
Check: Subtract coordinates: 8 minus 2 equals 6 for rise and 4 minus 1 equals 3 for run; divide 6 by 3 to get 2 and compare with the recorded slope.
Exercise 4
A line has y-intercept (0, 3) and slope 0. Record rise and run, plot three points, and state the slope check.
Show answer and check
Rise 0, run 1; points (0, 3), (1, 3), (2, 3); slope check gives 0.
Why: A slope of 0 means no vertical change. Start at (0, 3), move up 0 and right 1 to (1, 3), then repeat to (2, 3). The line is horizontal.
Check: Compute change in y as 3 minus 3 equals 0 and change in x as 1 minus 0 equals 1; divide 0 by 1 to get 0 and compare with the recorded slope.
Common mistakes
- Applying the run before the rise and losing count. Record rise and run in separate boxes, then apply rise first and run second from each marked point.
- Putting the negative sign on both rise and run for a negative slope. Attach the negative sign to exactly one of rise or run and state that choice in the side column.
- Using unequal grid spacing and treating diagonal moves as one unit. Confirm equal spacing on both axes and count only horizontal and vertical grid steps.
- Recording the y-intercept as a single number without the ordered pair. Write the intercept as an ordered pair so the starting point is unambiguous.
Self-check rubric
- Side column states a clear sign convention for rise and run.
- Y-intercept is recorded as an ordered pair in the marker space.
- Rise and run values are recorded in separate labeled boxes.
- At least three points are plotted using repeated rise and run steps.
- Plotted line passes through the recorded y-intercept.
- Slope check recomputes change in y over change in x and matches the record.
- Any valid sign placement on rise or run is accepted if the plotted direction matches.
Questions and answers
What goes in the rise and run boxes?
The signed vertical change goes in the rise box and the signed horizontal change goes in the run box. Together they form the slope as rise over run.
Can the negative sign go on the run instead of the rise?
Yes. A negative slope can be represented by a negative rise with a positive run, or a positive rise with a negative run. Record which choice you made.
How many points should be plotted before drawing the line?
Plot at least three points: the y-intercept and two points reached by repeating the rise and run. Three points make counting errors easier to detect.
What if the slope is a whole number?
Write the whole number as the rise and use 1 as the run, so the slope is the whole number over 1.
