Select the correct answer from each drop-down menu.
Polygon PQRS, shown in the figure, is dilated by a scale factor of 0.5 with the origin as the center of dilation, resulting in polygon P'Q'R'S'.
A polygon PQRS is plotted on a coordinate plane. The vertices P is at (10, 8), Q is at (6, 14), R is at (11, 16), and (15, 10).
The slope of P'Q' is
-1.5
.
The length of P'Q' is approximately
.
