the bridgeport water department has a monthly service charge of $13.20 and a usage charge of $1.42 for every 100 cubic feet of water. which of the following equations can be used to determine the monthly water bill of a bridgeport resident?

(let x represent the amount of water used in hundreds of cubic feet and y represent the monthly cost.)

a. y = 1.42x - 13.20

b. y = 14.62x

c. y = 1.42x + 13.20

d. y = 0.0142x + 13.20

Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x, y) ?
