Question

Which of the following points is not an ordered pair for the function

ƒ(x ) =5/2 x + 6?
4, 16)
(2, 7)
(-2, 1)

Answer 1

2,7

Explanation:

To solve this type of problem you simply plug the left number or x value in the ordered pair into the function and then see if it equals the right or y value. So we would plug 4 in for x and get 16, you then do the same thing for the other two pairs and find out that when you plug 2 into the equation, it does not equal 7
