-2y = -4x + 12
y = 2x - 6
y = -1/2x - 6
If all you want is just how this is written, then the answer is

That's the way it reads. However you may have meant
We cannot exactly tell from the wording what is meant. I would choose the first one, if this multiple choice. I would note the ambiguity if a person is doing the marking.

Y = 2x + b
3 = 2(2) + b, b = -1
Equation: y = 2x - 1
