Graph the line. x+y=4

So I need to graph this. So as not to feel guilty about just taking the answer..well lets say cheatingyeah I said it (Cringe) I dont like that. but whatever I tired solving it myself.

so here is what I did.

So I think I have to substitute x and y with any variable. So this is what I got...

2+2=4

so is the point (2,2)?
