9x^2+9y^2=36

9 x^{2} + 9 y^{2} = 36

(a, b) = (0, 0), r = 2

Solution steps

9 x^{2} + 9 y^{2} = 36

Rewrite

9 x^{2} + 9 y^{2} = 36

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (0, 0), r = 2

(x + 4)^{2} + y^{2} = 4

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

x^{2} + y^{2} - 2 y - 15 = 0

x^{2} + y^{2} - 8 x - 68 = 0

x^{2} + y^{2} + 2 x + 6 y - 104 = 0
