(x-7)^2+(y+9)^2=23

(x - 7)^{2} + (y + 9)^{2} = 23

(a, b) = (7, - 9), r = 23

Solution steps

(x - 7)^{2} + (y + 9)^{2} = 23

Rewrite

(x - 7)^{2} + (y + 9)^{2} = 23

in the form of the standard circle equation

(x - 7)^{2} + (y - (- 9))^{2} = (23)^{2}

Therefore the circle properties are:

(a, b) = (7, - 9), r = 23

x^{2} + y^{2} + 4 x - 8 y - 25 = 0

(x + 5)^{2} + (y - 5)^{2} = 25

x^{2} + y^{2} + 8 y + 1 = 0

x^{2} + y^{2} - 2 x - 4 y = 20

x^{2} + y^{2} - 4 x - 4 y - 9 = 0
