Answer:
Step-by-step explanation:
Trapezoid ABCD was dilated to create trapezoid A'B'C'D'.
Scale factor is 1/2 according to the coordinates.
The length of side AD is 8 units.
The length of side A'D' is 4 units.
The image is larger than the pre-image.
Sides CD and C'D' both have the same slope, 2.
Slopes of CD and C'D' are same: m = (0 - 4)/(4 - 2) = -4/2 = -2
The scale factor is One-half.
