Question

What is the scaling factor represented in this dilation?
-1/3
-3
3
1/3

Answer 1

Answer:

3

Step-by-step explanation:

From inspection, we can see that the dilated triangle (red) has side lengths that are 3 times bigger than the side lengths of the original triangle (blue).

Therefore, the scale factor for the dilation is 3 (about the origin)
