Step 7 Objective
Plot the graphs of linear functions, where y is given explicitly in terms of x; recognise that equations of the form y = mx + c correspond to straight-line graphs.

Examples of what pupils should know and be able to do
Plot the graphs of simple linear functions, e.g. y = 2x – 3 or y = 5 – 4x, using all four quadrants, by generating coordinate pairs or a table of values.
Recognise that a graph of the form y = mx + c corresponds to a straight line and represents an infinite set of points.
