You can work out the gradient m of the line by joining the point with coordinates (x1,y1) to the point with coordinates (x2,y2) by using the formula. m = y2 - y1 x2 - x1. It doesn't matter which point is taken as (x1,y1) Don't use this formula if you are just trying to figure out the equation of the line. 2. Equation of a Line with Gradient m ................
