Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
The independent variable is the # of hrs.
the dependent variable is # of gallons.
the slope is -125.
the y intercept is 13000

The probability of winning the gift card in the first place is always 1/8 no matter how many people have spun the gift card. That being said, by the same principal, the change of them both winning a gift card is 2/16 which reduces to 1/8. So the probability stays the same no matter what.
