Calculating the equation of a straight line from 2 points with answers

This follows on from an earlier resource where pupils had to plot the two points and record the y-intercept. Here, they are shown how to substitute a pair of coordinates into y=,mx + c, after they have calculated (m) (the gradient). The sheet gives clear steps to the working out and allows pupils to look at a worked example. Answers are provided.
