One-sixth
One-third
3
6

Answer 1

I can't see mc014-1.jpg — could you re-upload the image or describe the two figures (coordinates or corresponding side lengths)?

How to find the scale factor:
- Pick any corresponding segment (or coordinate).
- Scale factor = (length in image) ÷ (length in preimage).
- If using coordinates, divide a corresponding image coordinate by the preimage coordinate (e.g., (x',y') = k(x,y) so k = x'/x = y'/y).

Given the multiple choice:
- If the image is 6 times larger than the preimage → 6.
- If the image is 3 times larger → 3.
- If the image is 1/3 the size of the preimage → 1/3.
- If the image is 1/6 the size → 1/6.

Send the picture or the lengths/coordinates and I’ll pick the correct option.
