Solve.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 19 ounces of water. After it has been filling for 13 seconds, the gauge indicates the bottle contains 43 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 relates the amount of water in the bottle,y, to the time x.

x + 
B. y = 3x + 4
C. y = -3x + 34
D. y = 3x + 30
