Question

The rate of change is
A. -4
B. -1
C. 1
D. 4

Answer 1

-4

Explanation:

Each time 'x' changes by +1 the value of 'y' changes by -4

Answer 2

A. -4

Explanation:

Use the gradient formula (y2-y1)/(x2-x1)

Use the coordinates so (-2,17) = (x2, y2) and (-1, 13) = (x1, x2)

so 17-13/-2--1

= -4
