Question

Find the rate of change between (3, 8) and (6, 26)

Answer 1

6

Explanation:

The slope m between the 2 points is a measure of the rate of change.

Calculate m using the slope formula

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

with (x₁, y₁ ) = (3, 8) and (x₂, y₂ ) = (6, 26)

m =
`(26-8)/(6-3)` =
`(18)/(3)` = 6

Then rate of change is 6
