**Reiny**, Thursday, March 25, 2010 at 11:34amGeneral equation:

ax^2 + by^2 + cx + dy + e = 0

1) if a = b ---> circle

2) if both a and b are positive, but different, ---> ellipse

3) if a is positive and b is negative, ----> hyperbola

4) if either a or b, but not both, are zero ----> parabola

5) if both a and b are zero ---> straight line

so yours is a hyperbola
