Answer:
(12, 32); (-14,4)
Step-by-step explanation:
When you dilate a point from the origin by a scale factor, you multiply its coordinates by the same factor.
Thus, if the coordinates of the point are (3, 8) and the scale factor is 4, those of its image are (12, 32).
If the coordinates of the point are (28, 8) and the scale factor is -½, those of its image are (-14, -4),
The image below shows the dilation of your points.
