Question

The table represents a linear function. The rate of change between the points (-5, 10) and (-4,5) is -5. What is the rate of change between the points (3,0) and (-2, -5)!

Answer 1

rate of change (slope) = 1

Explanation:

rate of change (slope) is :

slope = (y2 - y1) / (x2 - x1)

(3,0)....x1 = 3 and y1 = 0

(-2,-5)...x2 = -2 and y2 = -5

now sub

slope = (-5 - 0) / (-2 - 3) = -5 / -5 = 1 <===
