Which set of ordered pairs is not a function? A. (3, 1), (–1,1), (1, 1), (3, −1) B. (–3, 1), (–1, 1), (1, 1), (3, 1) C. (–3, 1),

A set is NOT a function when there's an x-coordinate that is repeated, so let's check who is who.
Answer:
x = 12
Step-by-step explanation:
Proportional relationship means that 
= k(a constant)
Here, k = 12/8 = 3/2
So, the equation is = 3/2.
Plug in y = 18, and we get 18/x = 3/2.
18 = 3/2x
x = 12
Answer: not sure what you were trying to ask but two less than 15 is 13.
Answer:
The midpoint of A and B is (0, 4).
Step-by-step explanation:
Use the midpoint formula, ((x₁ + x₂)/2 , (y₁ + y₂)/2)
First, solve for the x part.
(2 + (-2))/2
0/2
0
So the x-coordinate of the midpoint is 0.
Then, solve for the y part.
(3 + 5)/2
8/2
4
So the y-coordinate of the midpoint is 4.
