Question

What is the rate of change between (29,9) and (33,10)?

Answer 1

`(1)/(4)`

Explanation:

The rate of change is a measure of the slope

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)

m =
`(10-9)/(33-29)` =
`(1)/(4)` ← rate of change
