How many months were you on the plan if you spent $400? Write just a number.
What is the coordinate for the y-intercept? Write something like (x, y) without any spaces, and substitute the correct numbers for x and y.

What equation describes this situation? Do not write any spaces. Write it in the form y=mx+b and substitute the correct numbers for m and b.

Is there a proportional relationship between time and the cost of the cell phone plan? Write either Yes or No
