The questions in this quiz are suitable for GCSE maths students studying coordinates, straight line graphs, y = mx + c, parallel and perpendicular lines and the equation of a line through two points.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x ...
