The slope (or average rate of change) formula is: . It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as and the other as . Then you insert these points into the slope formula (m represents slope). So, where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to .
