Solve. Assume the exercise describes a linear relationship. When writing a linear equation, write the equation in slope-intercept form.
2) 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 30 ounces of water. After it has been filling for 13 seconds, the gauge indicates the bottle contains 70 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= 5x + 5 B) y = QUOTE

x +29 C) y =- 5x + 55 D) y = 5x + 57
3) A gas station sells 4820 gallons of regular unleaded gasoline in a day when they charge $1.35 per gallon, whereas they sell 3880 gallons on a day that they charge $1.40 per gallon. Find a linear equation that relates gallons sold to price. Use this equation to predict the number of gallons sold at a price of $1.25 per gallon.
A) 6704.1 gallons B) 6696.7 gallons C) 6700 gallons D) 6709 gallons
4) The average value of a certain type of automobile was $15,660 in 1994 and depreciated to $6780 in 1997. Let y be the average value of the automobile in the year x, where x = 0 represents 1994. Write a linear equation that models the value of the automobile in terms of the year x.
A) y=-2960x - 2100 B) y =-2960x + 15,660 C) y =-2960x + 6780 D) y =-  QUOTE
