Question

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

Answer 1

`(1)/(7)`

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 =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

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

m =
`(-2+1)/(-3-4)` =
`(-1)/(-7)` =
`(1)/(7)` ← average rate of change
