Question

5.6 linear functions in the real world
enc has a small atv that gets 20 mile per gallon of gasoline. the atv has a 4 gallon gas tank that is full.
what is the y - intercept (b) in this situation?
the y - intercept (b) is miles per gallon of gas
the y - intercept (b) is gallons of gas in the tank over time.
the y - intercept (b) is miles traveled.
the y - intercept (b) is how much gas was in the tank at the beginning

Explanation:

The y - intercept of a linear function is the value of y when x = 0. In the context of the graph where x is miles traveled and y is gallons of gas in the tank, when 0 miles are traveled (x = 0), the amount of gas in the tank is the initial amount. Here, the ATV starts with a full 4 - gallon tank.

Answer:

The y - intercept (b) is how much gas was in the tank at the beginning.
