From the graph given
To find the hourly wage, we find the slope of the graph
The formula to find the slope, m, of a straight line graph is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where
[tex]\begin{gathered} (x_1,y_1)\Rightarrow(0,0) \\ (x_2,y_2)\Rightarrow(5,40) \end{gathered}[/tex]
Where the y coordinates represents the money earned and x coordinates represents the hours worked
Substitute the values of the coordinates into the formula of the slope above
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1}=\frac{40-0}{5-0}=\frac{40}{5}=\text{ \$8 per hour} \\ m=\text{ \$8 per hour} \end{gathered}[/tex]
Hence, the answer is option A
