Solve Assume the Exercise Describes a Linear Relationship $x$ Seconds After the Faucet Was Turned On

Multiple Choice

Solve. Assume the exercise describes a linear relationship.
-A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 5 seconds, the gauge on the bottle indicates that it contains 18 ounces of water. After it has been filling for 12 seconds, the gauge indicates the bottle contains 39 ounces of water. Let y be the amount of water in the bottle $x$ seconds after the faucet was turned on. Write a linear equation that models the amount of water in the bottle in terms of $x$ .

A) $y = 3 x + 3$
B) $y = \frac { 1 } { 3 } x + \frac { 49 } { 3 }$
C) $y = 3 x + 27$
D) $y = - 3 x + 33$
