Question

A cell phone plan cost $200 to start. then there is a $50 charge each month.

Answer 1

1. $250.00

2. y = 50x + 200

3. See below

4. Now, this is not a proportional relationship. The line does not go through the origin (0,0). The points on the graph in the form of y/x is not the slope nor proportional.

5. See below

Explanation:

1)

50 + 200 = 250

2)

y = the total cost

x = the number of months

y = 50x + 200

5. Parallel lines have the same slope but different y -intercepts. The equation of the line would be

y = 5x + 350. What this means is the the plan would cost the same per month, but the initial cost would be 350 rather than 200.
