Write the equation of the circle in standard form. Find the center and radius. Then sketch the graph.x2 + y2 + 2y - 3 = 0
A. x2 + (y + 1)2 = 4
(h, k) = (0, - 1), r = 2
B. (x + 1)2 + y2 = 4
(h, k) = (- 1, 0), r = 2
C. x2 + (y - 1)2 = 4
(h, k) = (0, 1), r = 2
D. (x - 1)2 + y2 = 4
(h, k) = (1, 0), r = 2
