Question

Rectangle ABCD is dilated by a scale factor of 1/2 with a center of dilation at the origin. What are the coordinates of the image of point b'

(–2, 3)
(3, –2)
(–8, 12)
(12, –8)

Answer 1

I think it's (-2,3).

Answer 2

B'(-2, 3)

Explanation:

Given the point B (-4,6)

In the question says that rectangle ABCD is dilated by a scale factor of 1/2 with a center of dilation at the origin.

So the point B' (x, y) is:

x =
`(1)/(2)`* (-4) = -2

y =
`(1)/(2)`* (6) = 3

=> B'(-2, 3) we choose A

Hope it will find you well.
