Answer:
The correct option is B.
Step-by-step explanation:
The line shows the relation between Anthony's earning and the number of hours he works.
From the given graph it is noticed that the line passing through (0,0) and (1,8).
Slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line is
[tex]m=\frac{8-0}{1-0}=8[/tex]
In the given graph x axis represents the times and y-axis represents the earning amount.
The value of slope is 8, it means the earning increased by $8 in each hour.
Therefore option B is correct. For each hour he works, his earnings go up by $8.
