(x-7)^2+(y-9)^2=9

(x - 7)^{2} + (y - 9)^{2} = 9

(a, b) = (7, 9), r = 3

Solution steps

(x - 7)^{2} + (y - 9)^{2} = 9

Rewrite

(x - 7)^{2} + (y - 9)^{2} = 9

in the form of the standard circle equation

(x - 7)^{2} + (y - 9)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (7, 9), r = 3

x^{2} + y^{2} = 32 + 14 y

(x - 4)^{2} + (y + 7)^{2} = 1 1^{2}

4 x^{2} - 4 x + 4 y^{2} = 63

x^{2} + y^{2} + 4 x + 6 y = 3

x^{2} + y^{2} + 4 x + 6 y = 0
