9. Dilate the figure by 1/2. Use the origin as the center of dilation.

10. Dilate the figure by 2. Use (-2,0) as the origin as the center of dilation.
To do this, you have to calculate the distance each point is away from the center of dilation and then multiply that distance by the dilation factor.

11. Find the center of dilation
