Question

Solve average rate of change (4,-1) (-3,-2)

Answer 1

Answer:

$\frac{1}{7}$

Step-by-step explanation:

The slope of the line joining the 2 points is a measure of the average rate of change.

Calculate slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 3, - 2)

m = $\frac{-2+1}{-3-4}$ = $\frac{-1}{-7}$ = $\frac{1}{7}$ ← average rate of change
