Answer:

The answer to your question is 5

Step-by-step explanation:

Rate of change of a linear function is the slope of the function.

To find the answer:

1.- Find two points of the line

A = (2, 4)

B = (1, -1)

2.- Write the formula of the slope

     m = (y2 - y1) / (x2 - x1)

3.- Identify the values of x1, y1, x2 and y2

       x1 = 2   y1 = 4  x2 = 1  y2 = -1

4.- Substitution

     m = (-1 - 4) / (1 - 2)

5.- Simplification

     m = -5/-1

6.- Result

     m = 5
