Question 1103268: Suppose you start with a full tank of gas (20 gallons) in your truck. After driving 3 hours, you now have 4 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.

Find an equation of a line in the form y = mx + b that describes the amount of gas in your tank

Suppose you start with a full tank of gas (20 gallons) in your truck. After driving 3 hours, you now have 4 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.
16/3 gallons/hour
====================
Find an equation of a line in the form y = mx + b that describes the amount of gas in your tank
y = (-16/3)x + 20
========================
Gas+=+20+-16t%2F3 - t in hours - makes more sense.
