-x^2-y^2=-1

- x^{2} - y^{2} = - 1

(a, b) = (0, 0), r = 1

Solution steps

- x^{2} - y^{2} = - 1

Rewrite

- x^{2} - y^{2} = - 1

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 1^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 1

- x^{2} - y^{2} + 2 x - 3 y + \frac{3}{4} = 0

(x - 5)^{2} + (y + 2)^{2} = 15

(x + 1)^{2} + (y - 4)^{2} = 30

2 x^{2} + 2 y^{2} - 8 x - 16 y + 22 = 0

x^{2} + y^{2} + 4 y + 1 = 0
