Which graph shows a dilation?

A
On a coordinate plane, 2 quadrilaterals are shown. The larger quadrilateral has points (negative 4, 3), (0, 3), (2, 0), and (negative 2, 0). The smaller quadrilateral has points (negative 2, 2), (0, 2), (0.5, 0), and (negative 1.5, 0).
Option A
B
On a coordinate plane, 2 quadrilaterals are shown. The larger quadrilateral has points (negative 4, 3), (0, 3), (2, 0), and (negative 2, 0). The smaller quadrilateral has points (negative 2, 2), (0, 2), (0.5, 0), and (negative 1.5, 0).
Option B
C
On a coordinate plane, 2 quadrilaterals are shown. The larger quadrilateral has points (negative 5, 3), (1, 3), (4, 0), (negative 2, 0). The smaller quadrilateral has points (negative 1, 0), (negative 2, 1), (0, 1), and (1, 0).
Option C
D
On a coordinate plane, 2 quadrilaterals are shown. The larger quadrilateral has points (negative 5, 3), (1, 3), (4, 0), (negative 2, 0). The smaller quadrilateral has points (negative 0.5, 0), (negative 1, 2), (1, 2), (1.5, 0).

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.
7

Which statements are true about the trapezoids? Select three options.

A
The length of side AD is 8 units.
B
The length of side A'D' is 4 units.
C
The image is larger than the pre-image.
D
Sides CD and C'D' both have the same slope, 2.
E
The scale factor is .
Option E
8

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.
9

Which statements are true? Select three options.

A
∠F corresponds to ∠F'.

C
The distance from point D' to the origin is the distance of point D to the origin.
Option C
D
The measure of ∠E' is the measure of ∠E.
Option D
E
△DEF △D'E'F'
Option E
10

Triangle MNP is dilated according to the rule DO,1.5 (x,y)(1.5x, 1.5y) to create the image triangle M'N'P, which is not shown.

B
M'(-6, 9) and N'(3, 9)
C
M'(-2, 3) and N'(7, 9)
