You figured out that you could make $50 each time you cleaned a pool during the summer. You did, however, need to purchase some equipment to get started. After cleaning 3 pools,
you were still down at total of 15 dollars. Write an equation in point-slope form that
represents that number of pools you clean, x, and the total amount you make in the summer,
V

a) y = 50x - 165   (After cleaning three pools, you were still down $15, this means the equipment costs 3*50 + 15 = $165)

b) The y-intercept -165 is the equipment cost

c) After cleaning 12 pools, y = 600 - 165 = 435. You have made $435.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
