The points (-15,3) and (-7,-1) both lie on the graph of the linear function y=f(x). What is the rate of change of f(x) with respect to x

-

Step-by-step explanation:

The measure of the rate of change of a linear function is the slope.

Calculate slope m using the slope formula

m =

with (x₁, y₁ ) = (- 15, 3) and (x₂, y₂ ) = (- 7, - 1)

m = = = - ← rate of change of f(x)
