-x^2+y^2-8y-9=0

Lösung

- x^{2} + y^{2} - 8 y - 9 = 0

Lösung

(h, k) = (0, 4), a = 5, b = 5

Schritte zur Lösung

- x^{2} + y^{2} - 8 y - 9 = 0

Rewrite

- x^{2} + y^{2} - 8 y - 9 = 0

in the form of a standard hyperbola equation

\frac{( y - 4 ) ^{2}}{5 ^{2}} - \frac{( x - 0 ) ^{2}}{5 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 4), a = 5, b = 5
