Question 623338
please help me answer this equation using slope intercept form x-y=1

 
                                          -x 
------------
What's the -x all by itself?

We don't "answer equations", we solve them for something.
You have one eqn and 2 variables --> an infinite # of "solutions", no unique solution.
-----------
If you graph it, you get a straight line, and every point on it is a solution.
