Linear Interpretation

The equation y = -0.05x + 16 shows the relationship between the miles driven, x, and the gas left in the tank, y. What is the meaning of the y-intercept?

• You start with 16 gallons of gas

• You lose 0.05 gallons each mile you drive.

• You gain 16 gallons of gas each mile.

• you start with -0.05 gallons of gas.
