Edexcel IGCSE Math A 3.3.I plot linear graphs

Practise linear-graph questions by completing values, plotting accurate points and drawing labelled straight lines from the given equations.

Exam points

Generate coordinate values from a linear equation before plotting the points.
Draw and label straight lines such as y = x + 1, x = 6 or y = 2x - 3 accurately.
Use the plotted graph to read values, intersections or line information.
