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