Exploring Scale Factor and the Point of Dilation

Explore the impact of scale factor and/or the location of point of dilation on the image. The pre-image cannot be moved.
Adjust just the scale factor. What happens to the image? If k>1 then the image is larger or smaller than the pre-image? Now keep the scale factor at one value (values greater than 2 are recommended). Move around the point P by clicking and dragging. Does the pre-image change size, location or both?
