Find the center and radius of (x + 9)^2 + (y + 6)^2 = 9.
a:
(-6, 9); 3
b:
(-9, -6); 3
c:
(9, 6); 3
d:
(-6, -9); 9

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
