To find the scale factor of a dilation from one set of coordinates to another, you can calculate the ratio of the change in the y-coordinates to the change in the x-coordinates.
Given the coordinates (4, -12) and (8, -16), the change in the y-coordinates is -16 - (-12) = -4, and the change in the x-coordinates is 8 - 4 = 4.
Thus, the scale factor of the dilation is |-4/4| = 1.
Note that taking the absolute value makes the scale factor positive, which indicates uniform scaling without reflection.
