Question

julie went hiking with her friends. the graph shows the distances they hiked over time. what is the slope of the line?

Explanation:

Step1: Recall slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Pick two points on the line

Use $(0, 0)$ and $(5, 20)$

Step3: Substitute into slope formula

$m = \frac{20 - 0}{5 - 0} = \frac{20}{5}$

Step4: Calculate the slope

$m = 4$

Answer:

4
