Write an equation in slope intercept form (from the table).

•   y = -3x

•   y = -8x

•   y = -4x + 4

•   y = -3x + 2

Refer to number 16 on your review for the scenario for this problem. 
16. a.  Write a system of equations in terms of x and y to model the situation.
(Which set of equations best represents your answer for 16 a?)

• 2x + 3y = 20
        xy = 44

• x + y = 20
        2x + 3y = 44

• 2x + 3y = 20
        2x + 3y = 44

• x + y = 44
        3x + 2y = 20
