Answer 1

2.5 inches per year

Explanation:

the slope m of the line gives the measure of the rate of change.

using the slope formula to find m

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

with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (4, 10) ← corresponding points for 2/ 4 years

m =
`(10-5)/(4-2)` =
`(5)/(2)` = 2.5

rate of change is then 2.5 inches per year

Answer 2

2.5 inches per year.

Explanation:

2 yrs= 5in

4 yrs= 10in

10in divided by 4 equals: 2.5in
