So, to make a graph for the equation $x-y=5$. I plugged in values for $x$ for example I used $0$ and $1$, For $0$ I plugged it in for $x$ and did this.
$0-y=5$ Then subtracted $0$ from both sides, which got me $-y =5$ I then divided $-y$ by both sides and got $-5$
Did I do this right? Am I supposed to divide y by both sides?
