Use the image to answer the question.
An illustration shows two graphs depicting earnings per hour for employees 1 and 2. The first graph shows earnings per hour for employee 1. The horizontal axis shows hours ranging from 0 to 8 in increments of 2. The vertical axis shows earnings in dollars ranging from 0 to 80 in increments of 5. Four data points are plotted on the graph at (0 , 0), (2 , 25), (4 , 50), and (6 , 75). A line connects all the data points. The second graph shows earnings per hour for employee 2. The horizontal axis shows hours ranging from 0 to 6 in increments of 1. The vertical axis shows earnings in dollars ranging from 0 to 80 in increments of 5. Four data points are plotted on the graph at (0 , 0), (1 , 15), (3 , 45), and (5 , 75). A line connects all the data points.
The earnings for Employee 1 and Employee 2 are displayed in the following graphs. Which employee earns more per hour?
To determine which employee earns more per hour, we can compare the slopes of the two lines on the graphs.
Looking at the first graph for Employee 1, as the hours increase by 2, the earnings increase by 25. This means that Employee 1 earns an additional $25 for every 2 hours worked.
Looking at the second graph for Employee 2, as the hours increase by 1, the earnings increase by 15. This means that Employee 2 earns an additional $15 for every 1 hour worked.
Since Employee 1 earns $25 for every 2 hours worked, and Employee 2 earns $15 for every 1 hour worked, it can be concluded that Employee 1 earns more per hour.
