Write the equation of the circle in standard form. Find the center and radius. Then sketch the graph.x2 + y2 + 2x + 6y - 15 = 0
A. (x + 1)2 + (y + 3)2 = 25
(h, k) = (-1, -3), r = 5
B. (x - 1)2 + (y + 3)2 = 25
(h, k) = (1, -3), r = 5
C. (x + 1)2 + (y - 3)2 = 25
(h, k) = (-1, 3), r = 5
D. (x - 1)2 + (y - 3)2 = 25
(h, k) = (1, 3), r = 5
