To find the scale factor of a dilation, you need to calculate the ratio between the corresponding side lengths of the two figures. In this case, the two points (4, -12) and (8, -16) represent the corresponding vertices of two figures.
The distance between the x-coordinates of the points is 8 - 4 = 4, and the distance between the y-coordinates is -16 - (-12) = -4. The negative value indicates a decrease in length.
The ratio of the corresponding side lengths is 4 / 4 = 1.
Therefore, the scale factor of the dilation is 1.
