    hint: total price = cost of boat + (price per hour)(number of hours)

    21.25 = (slope) + (money you paid up front)

    slope being the amount of money by each hour

    ok, 21.25 = (slope) + your y intercept (the money you paid up front)

    you 21.25 = (slope of money each hour) + 10 you paid 3.75 for each hour (or h) you spent on the boat

    so 3.75 is your slope 21.25 = 3.75h + 10 is your equation

    ok, so it should look like this 11.25 = 3.75h our objective is to get h by itself, so divide 3.75 to both sides
