Plotting Straight-Line Graphs
MA15-03
This lesson is coming soon.
In this lesson
Plot a straight-line graph from a table of values, using a ruler, extending the line across the full given range, and reading the axis scale correctly.
What it covers
- Building a table of values by substituting given x-values into the equation
- Plotting the resulting points accurately, reading the axis scale correctly (including scales that go up in steps other than 1)
- Joining the points with a single ruled straight line, drawn right across the full stated x-range, not just between the plotted points

For teachers
This GCSE Maths lesson teaches plotting straight-line graphs. By the end, students should be able to plot a straight-line graph from a table of values, using a ruler, extending the line across the full given range, and reading the axis scale correctly. It works through two worked examples and the mistakes examiners report.
