y^2-x^2-9=0

y^{2} - x^{2} - 9 = 0

(h, k) = (0, 0), a = 3, b = 3

Solution steps

y^{2} - x^{2} - 9 = 0

Rewrite

y^{2} - x^{2} - 9 = 0

in the form of a standard hyperbola equation

\frac{( y - 0 ) ^{2}}{3 ^{2}} - \frac{( x - 0 ) ^{2}}{3 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 3, b = 3

9 x^{2} - y^{2} - 36 x - 2 y + 44 = 0

t^{2} = 27 + u^{2}

\frac{x ^{2}}{81} - \frac{y ^{2}}{4} = 1

\frac{x ^{2}}{9} + \frac{8 x}{9} - \frac{y ^{2}}{9} + \frac{8 y}{9} - \frac{1}{81} = 0

x^{2} - y^{2} + 2 > 0
