Can an equation of a line in standard form be written in a way where A, B, or C are either negative or positive? It’s hard to explain… for example
-x+y=-2
Can that be a way to do it? Or would the correct way be like
x-y=2?
Or what about
2x-2y=4? Can I divide by 2 on both sides to rewrite it as
x-y=2? I’m just wondering….
