(x+1)^2+(y+5)^2=9

(x + 1)^{2} + (y + 5)^{2} = 9

(a, b) = (- 1, - 5), r = 3

Solution steps

(x + 1)^{2} + (y + 5)^{2} = 9

Rewrite

(x + 1)^{2} + (y + 5)^{2} = 9

in the form of the standard circle equation

(x - (- 1))^{2} + (y - (- 5))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- 1, - 5), r = 3
