The boundary of the inequality is an hyperbola with vertices (0,9) and (0,-9).
The asymptotes are y=9x/7 and y=-9x/7 which, of course, intersect at the origin.

(y^2 / 81) - (x^2 / 49) > 1 This is a difference of squares: (y/9 - x/7)(y/9 + x/7) > 1 63((y/9 - x/7)(y/9 + x/7)) > 63 (7y - 9x)(7y - 9x) > 6301/31/19
