The equation that would represent this situation is:

A = 2.5w + $12

To graph this you would substitute in varying numbers for w (the number of weeks) and this would be your x value in your ordered pair.

After you substitute in a number of weeks, you will get a total amount of money earned (A). This would be your y value in your ordered pair.

Here are some orders pairs you could plot to create the graph of this equation.

(1, 14.5)

(2, 17)

(3, 19.5)

(4, 22)
