Write the equation of the circle in standard form. Find the center and radius. Then sketch the graph.x2 + y2 - 8x + 2y + 8 = 0
A. (x - 4)2 + (y - 1)2 = 9
(h, k) = (4, 1), r = 3
B. (x - 4)2 + (y + 1)2 = 9
(h, k) = (4, -1), r = 3
C. (x + 4)2 + (y + 1)2 = 9
(h, k) = (-4, -1), r = 3
D. (x + 4)2 + (y - 1)2 = 9
(h, k) = (-4, 1), r = 3
