Sorry, but the text of your question doesn't make sense ... (Worried)

The given equation describes a plane which passes through the origin and it's normal vector is $\displaystyle \vec n = (1,1,-1)$.

And the intersection of this plane with one of the coordinate planes (xy, xz or yz) is a straight line. Therefore the given plane isn't parallel to any of the three coordinate planes.

But as I mentioned above there isn't a xyz plane.
