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

{(-2, 8), (1,5), (4,2), (7, -1)} represents a linear function.

Step-by-step explanation:

In order to get from an x-value of -2 to 1 you add 3.

In order to get from a y-value of 8 to 5 you subtract 3.

This pattern is consistent with each coordinate in the ordered pair.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

good luck on your studies! : )
