The equation y = mx + c, as anyone who has done GCSE maths should know, represents a straight line graph running from bottom left to top right. Any party leader, or indeed any politician ...

To work out the equation of a line from a graph, find the gradient and the \(y\)-intercept. The gradient is the same all along the line, so it doesn’t really matter where you start or finish ...
