To find the slant (or "oblique") asymptote, do the polynomial long division. Whatever you get across the top of the division is your other asymptote.

Code:
        x  - 1
      -------------
x + 1 )x^2 + 0x + 0
       x^2 + 1x
      -------------
            -1x + 0
            -1x - 1
      -------------
                  1
