Question

A parking garage opens at 8am. Some cars are parked in the garage overnight. The graph shows the total number of cars in the garage. What is the slope for this graph?

Answer 1

The slope of this graph is
`m=2(cars)/(minute)`

Explanation:

Define the variables

Let

x -----> the number of minutes past 800 am

y ----> the number of cars

we know that

The formula to calculate the slope between two points is equal to

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

Looking at the graph take two points

(0,60) and (20,100)

substitute the values in the formula

`m=(100-60)/(20-0)`

`m=(40)/(20)`

`m=2(cars)/(minute)`
