All right, let's graph x minus y equals two by creating an xy table, picking values for x, substituting them into the equation, and then solving for the corresponding y value.
00:15
So when x equals negative 2, negative 2 minus y equals 2, this is our x value in the equation.
00:27
And we need to isolate for y.
00:29
So we're going to add two to both sides to get started.
00:33
You're left with negative y equals four.
00:37
Now the y is not officially isolated yet.
00:39
That negative in front you could think of as like a negative one that we would need to get rid of.
00:45
So we can do that by dividing by negative one to both sides.
00:51
So y equals negative four.
00:55
All right.
00:56
Next we have x equals 0...
