Start with the given system of equations:


system%28x-y=1%2Cx%2By=-1%29


In order to graph these equations, we must solve for y first.


Let's graph the first equation:


x-y=1 Start with the first equation.


-y=1-x Subtract x from both sides.


y=%281-x%29%2F%28-1%29 Divide both sides by -1 to isolate y.


y=x-1 Rearrange the terms and simplify.
