y=x and y=x+2 Do these lines intersect when graphed?

I think I can substitute any number for x, but I'm not sure. I also do not think the lines will intersect, but I'm not sure. please simplify:

4 over ax+ay-bx-by minus 3 over a-b...all of this OVER

2 over a-b plus 2 over x^2 + xy

so it should look like:

4.....................3
-------- minus
