Answer:
(2, 4)
Explanation:
You want the coordinates of point J' given J(4, 8) and dilation by a factor of 1/2 about the origin.
Dilation
Dilation about the origin multiplies each coordinate value by the scale factor:
J' = 1/2(J)
J' = 1/2(4, 8) = (2, 4)
The coordinates of point J' are (2, 4).

Additional comment
You will notice that J' is the midpoint of the segment between J and the origin, because the scale factor is 1/2.
