Which set of ordered pairs represents a function? {(-3, 4), (-7, 2), (-7, -4), (-9, -5)}
{(-2, 4), (0, 5), (-9, 9), (-9, 7)}
{(-4, -6), (-7, -5), (-4, -7), (1, 1)}
{(5, -2), (-8, -6), (4, -2), (-6, 3)}

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
