an employee earns an hourly wage shown in the graph below. find the hourly wage. dollars per hour

Answer:

20

Explanation:

Step1: Identify two points

Let's take two points on the line: (0,0) and (2,40).

Step2: Use slope - formula

The slope formula for a line $y = mx + b$ (where $m$ is the slope and in the context of earnings per hour, $m$ is the hourly wage) is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=2,y_2 = 40$. So $m=\frac{40 - 0}{2 - 0}=\frac{40}{2}=20$.
