Based on the information given, which bathtub will be empty of water first?

Find the slope of each.
A) (15-27) / (8-0) = -12/8 = -1.5
Tub A is draining at 1.5 gallons a minute.
B) (17-25)/(6-0) = -8/6 = -1.33
Tub B is draining at 1.33 gallons per minute.
Tub B is draining faster so will be empty first.
