Final answer:
The coordinates of the image after dilation by a scale factor of 5 are (0, -10).
Step-by-step explanation:
To dilate a point, we multiply its coordinates by the scale factor. In this case, the scale factor is 5. So we multiply the x-coordinate of point G by 5 to get 0 * 5 = 0, and we multiply the y-coordinate of point G by 5 to get -2 * 5 = -10. Therefore, the coordinates of the image of point G after dilation by a scale factor of 5 are (0, -10).
