Algebra I

I am tying to determine whether the graph pairs below are parallel. x+12=y and yx=8. I have found the slope to x+12=y is 1. But I can't determine the slope for for yx=8. I am thinking maybe it is undefined, but I am not sure, since I am really new at this algebra. Any help would be appreciated. Thanks

The pairs should be parallel. yx=8 in slope intercept form ( y=mx+b) is y=x  8. So the slope for yx=8 is 1 too.
