a^2=8-2b-b^2

a^{2} = 8 - 2 b - b^{2}

(a, b) = (0, - 1), r = 3

Solution steps

a^{2} = 8 - 2 b - b^{2}

Rewrite

a^{2} = 8 - 2 b - b^{2}

in the form of the standard circle equation

(a - 0)^{2} + (b - (- 1))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (0, - 1), r = 3

(x - 1)^{2} + (y - 3)^{2} = 9

(x + 3)^{2} + (y - 4)^{2} = 36

x^{2} + y^{2} = 42

x^{2} + y^{2} = 52

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