when rewritten your equation in the problem is y=x-2
You need to find an answer that when put with the equation above, cancels it out resulting in no solution because the slopes are the same
The equations rewritten are
y=5
y=x-4. This one is the answer.
y=-x+2
y=-x+2
You plug in y=x-2 into y=x-4 so it’s
x-2=x-4
The Xs will camel resulting in no solution
