Which set of ordered pairs does not represent a function?
{(3,-5), (-3,-5),(-6,2), (-4,6)}
{(0, -1), (7,-6), (6, -5), (9,-6)}
{(-1,7), (-6, -9), (-5,8), (-1,9)}
{(-2,-2), (3, -8), (-9, -8), (-3,2)}

The third set

Step-by-step explanation:

The third set does not a represent a function because you cannot have the one x value produce two different y values.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

y + 11 = (1/4)(x + 16)
