If you are talking about y as in y = mx + b then i can help you.
Let’s use this example:
3x + 4y + 2 = 16
What you first need to do is get y alone on one side of the equation. The way we do this is by subtracting 2 from both sides. That gives us 3x + 4y = 14
After this let’s move the x over to the other side into point slope form. 4y = -3x + 14
Now just divide everything by 4.
The answer is y = -3/4x + 7/2
