A 1700-gallon tank is initially full of water. The water is drained at a rate of 16 gallons per minute. Write a linear equation, in slope-intercept form, that models this situation. (Note: "y =" is already given -- just enter the right side of the equation.) y = In the equation, the variable x represents which of the following? (Choose one) time elapsed while water drains (minutes) amount of water drained from the tank (gallons) rate at which water drains (gallons per minute) amount of water still in the tank (gallons) In the equation, the variable y represents which of the following?
