We are given that a car starts a journey with a full tank of gas. The equation $y=16-0.05x$ relates the number of gallons of gas (y) left in the tank to the number of miles the car has traveled(x).

A. We will find y intercept by substituting x=0 in our equation,

$y=16-0.05*0$

$y=16$

Now let us find our x-intercept by substituting y=0 in our equation,

$0=16-0.05x$

$0.05x=16$

$x=\frac{16}{0.05}=320$

Therefore, x-intercept is 320 and y-intercept is 16.

B. Our x-intercept represents that after travelling 320 miles there were 0 or none gallons of gas left in tank.

C. Our y-intercept represents that there were 16 gallons of gas in car tank when car started the journey.
