Question 9: Please help, what would be the length of the image of the segment GH?

Answer:
Explanation:
You can use the center of dilation as your origin of coordintes.
Thus, the point H would have coordinates (0,0) and the point G (-1,0).
A dilation multiplies the coordinates by the scale factor. Hence:
Thus, the length of the image of segment GH would be the distance from 0 to -5 in a number line, which is 5.
