Question

pretest: unit 1 look at the graph. what is the slope of the line? distance (miles) time (hours) a. -1 b. 5 c. 1 d. 0

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Select two points

Let's take two points on the line, say $(1,5)$ and $(2,5)$. Here $x_1 = 1,y_1=5,x_2 = 2,y_2 = 5$.

Step3: Calculate the slope

$m=\frac{5 - 5}{2 - 1}=\frac{0}{1}=0$.

Answer:

D. 0
