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?

A) 1
B) 2
C) 3
D) 5

Answer 1

The slope is 2, as for every 20 the graph rises, the line goes over 10, and the formula for slope is rise over run.

Answer 2

Answer is option B) 2

Explanation:

A parking garage opens at 8 am. The given graph shows number of cars at y axis and time at x axis.

Now we have to find the slope of the line shown in the graph.

This line passes through two points (0, 60) and (10, 80)

Slope of a line is represented by
`m=(y-y')/(x-x')`

Now we put the values in the formula

`m=(80-60)/(10-0)=(20)/(10)`

m = 2

Therefore, answer is option B) 2
