A four-sided figure is resized to create a scaled copy. The proportional relationship between any given side length in the original figure, f, and the corresponding side
length in the scaled copy, s, can be represented by the equation s = - f. What is the
constant of proportionality from side lengths in the original figure to side lengths in
the scaled copy?
