Answer :
Answer:
(d)
Step-by-step explanation:
The equation of a circle in standard form is
• (x - h )² + (y - k )² = r²
(h, k ) are the coordinates of the centre and r is the radius
here centre = K (- 1, - 1 ) , with h = - 1 and k = - 1 and radius r = 3 , then
(x - (- 1) )² + (y - (- 1) )² = 3² , that is
(x + 1 )² + (y + 1 )² = 9
