Line segments AB and CD bisect cach other at point K(6, 4). Which could be the coordinates of points A, B, C, and D ? A. A(2, 1), B(4,3), C(1, 1), D(5,0)
C. A(3, 2), B(9,6), C(2, 6), D(4,0)
B. 1(-1.3), B(13, 5), ((4.7), D(8,1) D. A(-2, -1), B(10, 13), C(2, 9), D(6, 3)

Some explanation would be greatly appreciated
