Question

look at the graph. what is the slope of the line? velocity (m/s) time (seconds) a. 6 b. 5 c. 3 d. 4

Explanation:

Step1: Select two points

Let's take the points (1, 10) and (2, 15).

Step2: Use slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 1,y_1=10,x_2 = 2,y_2 = 15$. So $m=\frac{15 - 10}{2 - 1}$.

Step3: Calculate the slope

$m=\frac{5}{1}=5$.

Answer:

B. 5
