Answer:
either 5 or 11
Step-by-step explanation:
(8, -12)
(5, -9) or (11, -9)
If y varies consistently with x then it would copy what happens, in a manner of speaking.

I am not completely sure on this.
A is the correct answer
(to find diagonal of a square , you can get help from Pythagorean Theorem)

good luck
This is some simple Algebra
So it's 4x+16=-2

4x=-18
Sivide both sides by 4
X=-4.5
If you need more of an explanation I am happy to elaborate

can you do
5=-3k+7?
