Question

I need help on this question in math

Answer 1

The rate of change or essentially the slope is a numerical value that describes the direction and the steepness of the line.

To find the slope, we just need any two points on the line

--> Let's pick (0,2) and (2,6)

The slope's equation =
`(y2-y1)/(x2-x1)`

Let's plug the known quantities into the equation

`(y2-y1)/(x2-x1)=(6-2)/(2-0) =(4)/(2) =2`

Therefore the rate of change is 2 km/trip

Hope that helps!
