Ifa line segment has a length of 12 units and after a dilation the image length is 4 units, what was the scale factor?
A. 1/3
B. 3
C. 8

Work Shown:

x = preimage length = 12

y = image length = 4

z = scale factor

z = y/x

z = 4/12

z = (1*4)/(3*4)

z = 1/3

The scale factor is 1/3.

This means the image is 1/3 of the length of the preimage.
