Question

complete the statement that describes the situation. the car is traveling at 30 miles per hour when stevens mom starts slowing down. as stevens mom slows down, the cars speed decreases by miles per hour every second.

Explanation:

Step1: Identify two points on the line

We can take the points (0, 30) and (2, 18).

Step2: Use slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1=30,x_2 = 2,y_2 = 18$. Then $m=\frac{18 - 30}{2-0}=\frac{- 12}{2}=-6$.
