Answer:
<h2>A 90° clockwise rotation about the origin and a translation of 7 units down.</h2>Step-by-step explanation:
First of all, we need to define the image and pre-image.
- The pre-image is the rectangle ABCD, before the transformation.
- The image is the rectangle A'B'C'D', after the transformation.
Second, let's write down the coordinates of each rectangle.
ABCD coordinates:
A(-6,5)
B(-1,5)
C(-1,1)
D(-6,1)
A'B'C'D' coordinates:
A'(5,-1)
B'(5,-6)
C'(1,-6)
D'(1,-1)
The first rule we need to apply is the 90° clockwise rotation which is
Which gives us (5,6), (5,1), (1,1), (1,6).
Then, we use the 7 units-down rule
Which gives us (5,-1), (5,-6), (1,-6) and (1,-1).
Therefore, the right answer is the third choice.
