WEBThe average rate of change takes two points and calculates (y2 - y1)/(x2 - x1). It's not really accurate for the actual rate of change at the first point, though. So by bringing the second point closer and closer to the first point, we get closer and closer to the actual rate of change at that first point.

WEBIn the x-y coordinate system, the average rate of change formula is the slope formula. The slope formula is given as: $$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$$ This gives us the average rate of change between the points (x 1, y 1) and (x 2, y 2). See the image below for a visual of average rate of change between two points on a function.
