OH MY GOSH! I AM SO SORRY! Hahaha I was doing the wrong thing. 

Look at your answers. They are in the form of (x,y)

anonymous · Answer

It's ok, hehe. I get confused like that too.

animelover98 · Answer

So, use your original equation.
2x+y=5
So, let's use choice b.
Plug the numbers in (3,-1).
3=x and -1=y
