Answer:

A. (-2,3)

Explanation:

Rectangle ABCD is dilated by a scale factor of 1/2.

Scale factor of k with a center of dilation at the origin:


(x,y)
(kx,ky)

It is given that rectangle ABCD is dilated by a scale factor of 1/2 with a center of dilation at the origin, then:


((1)/(2)x,(1)/(2)y)

The coordinates of B are (-4,6). So, the coordinates of B:


B(-4,6)
B((1)/(2)(-4),(1)/(2)(6)


B(-4,6)
B(-2,3)

The coordinates of B → (-2/3)

Hence, -2/3 is the correct answer.
