A two rectangles on a Coordinate Plane. The larger rectangle has vertices labeled A', B', C', and D', while the smaller rectangle inside has vertices labeled A, B, C, and D. The larger rectangle A'B'C'D' appears to be a scaled-up version of the smaller one what is located within it. Both rectangles are aligned with the axes, indicating that their sides are parallel to the x and y axes.

What is the transformation from rectangle $ABCD$ABCD to rectangle $A'B'C'D'$A′B′C′D′?
