(x-2)^2+(y+7)^2=49

(x - 2)^{2} + (y + 7)^{2} = 49

(a, b) = (2, - 7), r = 7

Solution steps

(x - 2)^{2} + (y + 7)^{2} = 49

Rewrite

(x - 2)^{2} + (y + 7)^{2} = 49

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (2, - 7), r = 7
