Serenity filled up her car with gas before embarking on a road trip across the country. Let G represent the number of gallons of gas
remaining in her gas tank after driving for t hours. A graph of G is
shown below. Write an equation for G then state the y-intercept of the
graph and determine its interpretation in the context of the problem.
