On a separate piece of paper, answer the following and take a picture then upload it:

Part A: Graph the cost of the cell phone plan over a period of two years, using months as the unit of time. Be sure to label your axes and scale them by labeling each gridline with a number.

Part B: Is there a proportional relationship between time and the cost of the cell phone plan? Explain how you know.
