Question

Jose filled up his car with gas before embarking on a road trip across the country. Let G represent the number of gallons of gas remaining in his gas tank after driving for t hours. A graph of G is shown below. Write an equation for G then state the x- intercept of the graph and determine it's interpretation in the context of the problem.

G = _______
The x-intercept of the function is ____ which represents _____ .​

Answer 1

G= -6/5x+15

X intercept is 12 and it means the gas runs out after 12 hours

Explanation:

the slope is using rise over run is 6/5 but since it’s going down it’s negative and the y intercept is 15 since it intersects at this point
