Calls on Gary's phone cost an initial 6 cents, then 8 cents per minute. The table below shows the cost of calls that last 0, 5, 10, 15, and 20 minutes. Represent the linear relationship between the number of minutes Gary talks, x, and the total cost of a call, y, in two more ways: as an equation and as a sentence.

the X's go up by 5 between points. the Y's go up by 40 between points.
