Can someone help me?? Fan and medal (Geometry)

Octagon ABCDEFGH and its dilation, octagon A'B'C'D'E'F'G'H', are shown on the coordinate plane below

Answer 1

If the center of dilation is at the origin, by what scale factor was octagon ABCDEFGH dilated

Answer 2

one half

2

4

one quarter

Answer 3

The scale factor is \(\displaystyle \frac{X'}{X}\) where you can choose \(X\) to be any point which is scaled except for the origin. If you choose \(X = A\), the scale factor is \(\displaystyle\frac{A'}{A} = \frac{(6, 2)}{(3, 1)} = \frac{2(3, 1)}{(3, 1)} = 2\).
