The x-axis is the time worked in hours, the y-axis is the amount of $ earned.
Slope is the constant rate of change. It is a certain amount of $ earned for a certain number of hours. So as the the number of hours you work increases, the amount of money you earn also increases.
[tex]Slope = \frac{rise}{run}[/tex]
Rise is the number of units you go up or down (y)
Run is the number of units you go to the right (x)
Basically, your answer is B.
