-y^2-x^2=-9

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

(a, b) = (0, 0), r = 3

Solution steps

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

Rewrite

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

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 3

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

2 x^{2} + 2 y^{2} - 16 y + 24 = 0

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

(x - 4)^{(2)} + (y + 10)^{(2)} = 144

x^{2} + 6 x + 9 + y^{2} - 2 y + 1 = 54 + 9 + 1
