9y^2-16x^2-18y-64x-199=0

9 y^{2} - 16 x^{2} - 18 y - 64 x - 199 = 0

(h, k) = (- 2, 1), a = 4, b = 3

Solution steps

9 y^{2} - 16 x^{2} - 18 y - 64 x - 199 = 0

Rewrite

9 y^{2} - 16 x^{2} - 18 y - 64 x - 199 = 0

in the form of a standard hyperbola equation

\frac{( y - 1 ) ^{2}}{4 ^{2}} - \frac{( x - ( - 2 ) ) ^{2}}{3 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (- 2, 1), a = 4, b = 3

6 y^{2} - 3 x^{2} = 6

9 y^{2} - 16 x^{2} - 64 x - 54 y - 127 = 0

y^{2} = x^{2} + 2 x - 15

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

9 y^{2} - 4 x^{2} - 36 = 0
