Question

ΔRST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6). Which scale factor was used to perform the dilation?

Answer 1

To find the scale factor, divide the first coordinates by the second coordinates:
x-coordinates:
3÷1.2 =2.5
y-coordinates:
9÷3.6=2.5
The scale factor is:
2.5

Answer 2

Incorrect. The scale factor is a ratio of the x- and y-coordinates in the image to the x- and y-coordinates in the preimage. Here, the scale factor is 0.4.

Answer 3

gg

Answer 4

The scale factor is the ratio of R'O¯¯¯¯¯¯ to RO¯¯¯¯¯, where O is the origin.

Answer 5

oh

Answer 6

1.2/3 = 0.4

3.6/9 = 0.4
