if you are trying to graph it, then you need to simplify it to simplest linear slope form: y = mx + b
As of now, you have 2x - 2y + 5 = 0
Isolate the y to one side of the equation, -2y = -2x - 5
Divide the entire equation by -2, to completely isolate the y,
y = x + 5/2
Basically, y = x + 5/2 and x = y - 5/2
