Suppose you start with a full tank of gas (17 gallons) in your truck. After driving 3 hours, you now have 3 gallons left.
If x is the number of hours you have been driving, then y is the number of gallons left in the tank.
At what rate is your truck using gas? State your answer as a reduced fraction.
______ gallons per hour
Find an equation of a line in the form y = mx + b that describes the amount of gas in your tank.
y=________

Find an equation of a line in the form y = mx + b that describes the amount of gas in your tank.
y=________
-
(17 - 3)/3 = 14/3 gal/hr
y = 17 - 14h/3 where h is the amount of hours of driving.
y = 17 - 14h/3 where h is the amount of hours of driving.
