Find the center and radius of (x + 9)^2 + (y + 6)^2 = 9.

VARVARA [1.3K]

You can do this by comparing your equation to the general form of equation of a circle

( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9

so (a,b) = (-9,-6) and r = 3

so the answer is B
