Plotting Linear Graphs
Plot linear graphs by generating a table of values, reduce a two-variable linear equation to the form y = mx + c, and calculate gradients from two points on a line
Suggested ages 12–14
Evidence of understanding
- Generate a table of (x, y) values for a linear equation and plot the points accurately
- Rearrange an equation such as 2x + 3y = 12 into the form y = mx + c
- Calculate the gradient between two coordinate points using rise over run
Assessment prompt
Can Plotting Linear Graphs draw the graph of a straight line by making a table of values and plotting the points — and work out the gradient from two points on the line?
