the graph below shows the earnings roland receives for the hours that he works. which statement is true based on the information in the graph? roland earns $5 per hour. roland earns $8 per hour. roland earns $20 per hour. roland earns $40 per hour.

Answer

Explanation:

Step1: Recall slope - rate formula

The rate of earnings per hour is the slope of the line in the graph. The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.

Step2: Select two points

Let's take two points from the graph: $(0,0)$ and $(40,200)$.

Step3: Calculate the slope

$m=\frac{200 - 0}{40 - 0}=\frac{200}{40}=5$.

Answer:

Roland earns $5 per hour.
