It's at (0, 0), if I think I know what your talking about, you didn't make it to clear.
If the whole problem consists of the line y = x, then the only intercepts would be the vertical and the horiz. intercepts.  In this case, these intercepts are the same:  (0,0).  

To see this, graph (0,0), and then draw the line y = x through it.

I don't believe there's any such word as "pointment."
