Topic: Coordinates and Graphs (Foundation - Unit 2)

Specification References: N6.4 N6.4 Recognise and plot equations that correspond to straight-line graphs in the coordinate plane, including finding their gradients.

Candidates should be able to:

• recognise that equations of the form y = mx + c correspond to straight line graphs in the coordinate plane
• plot graphs of functions in which y is given explicitly in terms of x or implicitly
• complete partially completed tables of values for straight line graphs
• calculate the gradient of a given straight line using the y-step/x-step method

Notes

Foundation tier candidates will not be expected to plot graphs using the gradient–intercept method.

Foundation tier candidates will not be expected to know that m represents gradient and c represents the y-intercept.

Examples

1. Plot the graph of (table of values will not be given).
