Question

Given the pre-image point A (4,-9) and it's image point A' (12, -27), determine the scale factor

Answer 1

Answer:

scale factor = 3

Step-by-step explanation:

To determine the scale factor, calculate the ratio of the image x and y coordinates to the original x and y coordinates, that is

scale factor = $\frac{12}{4}$ = $\frac{-27}{-9}$ = 3
