How do you calculate the rate of change?

The term 'rate of change' refers to the slope of the line that connects the two points of the line. If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.

When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.

BRAINLIEST PLS :)
thanks!
