Question

This graph represents the relationship between the number of hours a babysitter worked in the amount of money in dollar she earned what is the amount of money in dollars the babysitter earned for each hours she worked

Answer 1

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:

$Slope,m=\frac{y_2-y_1}{x_2-x_1}$

This should give the amount earned per hour.
