To determine the amount of money earned per hour by the babysitter, we calculate the rate of change/slope of the line.

This is done by first picking two points on the line.


(x_1,y_1)\text{ and }(x_2,y_2)

That is, for each point, trace it to the x and y-axis.

Next, substitute the points into the slope formula below:


Slope,m=(y_2-y_1)/(x_2-x_1)

This should give the amount earned per hour.
