What is Dilation on the Coordinate Plane Guide about?

Dilation changes the size of an object by multiplying the coordinates of its points by a scale factor while preserving shape. To dilate a figure: (1) find the scale factor by changing the percent dilation to a decimal, (2) multiply the original coordinates of each point by the scale factor. For example, to dilate quadrilateral ABCD with a 150% dilation, the scale factor is 1.5. Multiplying the original coordinates of A(-2,0), B(-2,4), C(2,6), and D(6,-2) by 1.5 results in the dilated coordinates of A
