Question

Can anyone help me with this question?

Answer 1

Explanation:

The rate of change or slope is defined as

m=(y2-y1)/(x2-x1)

Using any two points on the line we can find this rate of change, I’ll use points

(0,2) and (4,10) then

m=(10-2)/(4-0)

m=8/4

m=2

So he travels 2 kilometers per trip.
