Answer:
The scale factor is 3.
Step-by-step explanation:
Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).
Therefore, the distance OA is given by units.
Again, the coordinates of point A' are (1,-2).
Therefore, the distance OA' is given by units.
Hence, the scale factor is . (Answer)
