Okay, here we have this:
Considering the provided information, we are going to find the x- and y- intercepts and explain its meaning. So we obtain the following:
Since the x-intercept is the point where the Graph intersects the x-axis (y=0) and the y-intercept is the point where the Graph intersects the y-axis (x=0), we have that:
x-intercept=(300, 0)
y-intercept=(0, 16)
Since the y-axis represents the number of gallons, and the x-axis time, then the y-intercept indicates that when filling the tank it was left with 16 gallons, and the x-intercept indicates that when emptying the tank had traveled 300 miles.
