What is true about the image ΔQ'R'S'? Select three options.Which statements are true?

A
DO,2 (x,y) = (2x, 2y)
B
Side Q'S' lies on a line with a slope of -1.
C
QR is longer than Q'R'.
D
The vertices of the image are closer to the origin than those of the pre-image.

On a coordinate plane, trapezoids A B D C and M N P Q are shown. The length of A B is 4 units and the length of B D is 2 units. The length of M N is 10 units and the length of N P is 6 units.

Question illustration
A
Yes, because AB and CD are each the lengths MN and QP.
Option A
B
Yes, because sides AB and CD are parallel to sides MN and QP.
C
No, because AB is the length MN but CD is the length QP.
Option C
D
No, because sides AB and CD have different slopes from sides MN and QP.

On a coordinate plane, 2 quadrilaterals are shown. Quadrilateral A B C D has points (2, negative 2), (4, negative 2), (3, negative 4), and (1, negative 4). Quadrilateral J K L M has points (4, negative 4), (8, negative 4), (6, negative 9), and (2, negative 9).

Question illustration
A
Yes, because sides JK and ML are twice as long as sides AB and DC.
B
Yes, because both figures are parallelograms, so corresponding sides are parallel.
C
No, because sides JK and ML are not twice as long as sides AB and DC.
D
No, because sides JM and KL have different slopes from sides AD and BC.
