-x^2+9y^2=9

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

(h, k) = (0, 0), a = 1, b = 3

Solution steps

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

Rewrite

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

in the form of a standard hyperbola equation

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

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 1, b = 3

(x + i y)^{2} + (x - i y)^{2} = 2

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

y^{2} = x^{2} + 25

y^{2} = x^{2} + 49

x^{2} - 4 x - 4 y^{2} - 8 y - 16 = 0
