(x+2)^2+(y-2)^2=4

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

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

Solution steps

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

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

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

x^{2} + y^{2} - 12 = 0

x^{2} - 4 x + y^{2} + 10 y = - 25

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

x^{2} + y^{2} + 10 x + 4 y + 4 = 0
