Answer:

B. For each hour he works, his earnings go up by $14.

Step-by-step explanation:

Given

The attached graph

Required

The true statement

The attached graph is a linear graph.

From the graph, we have:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (1,14)[/tex]

The rate (m) is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{14-0}{1-0}[/tex]

[tex]m = \frac{14}{1}[/tex]

[tex]m = 14[/tex]

This implies that the hourly rate is $14/hr

Hence (b) is true
