What is the rate of change of the linear function that has a graph that passes
hrough the points (3, 10) and (-2, 4)?

Answer 1

6/5 or 1.2

Explanation:

Average rate of change of a function f(x) between the interval [a, b] is:

[ f(b) − f(a) ] / (b − a)

[ f(3) − f(-2) ] / (3 − (-2))

(10 − 4) / (3 + 2)

6/5 = 1.2
