[Foundation and Higher] Find approximate solutions to linear equations using a graph.

[Foundation and Higher] Find approximate solutions to linear equations using a graph. is assessed within Solving equations and inequalities. Linear graphical solutions come from reading where a straight line reaches a required value or crosses another line. Students should identify the relevant line, locate the intersection or intercept, and read the coordinate using the graph scale. This is different from quadratic graphical solving because there is normally one straight-line crossing rather than a curved graph with two roots. For exam answers, show the chosen representation, calculation step or graph reading before giving the final value.
