Suppose you start with a full tank of gas (17 gallons) in your truck. after driving 4 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. incorrect 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 =

Part a) The rate is equal to

Part b)

Step-by-step explanation:

step 1

Let

x-----> the number of hours

y----> the number of gallons left in the tank

we know that

For -----> represent the y-intercept

For

Find the rate (slope of the linear equation)

simplify

step 2

Find the equation of the line

the equation of the line in slope intercept form is equal to

we have

substitute

the answer is a
