When describing a rotation, the applicable direction is **counterclockwise**.

To accurately describe the transformation, we would need to see the diagram in question. However, if you can provide details on the position of the points before and after the transformation, I can help you determine which description fits best.
If you are looking for general guidance:
- A **180° counterclockwise rotation about the origin** will take a point (x, y) to (-x, -y).
- A **90° clockwise rotation about the origin** will take a point (x, y) to (y, -x).
- A **270° counterclockwise rotation about the origin** is equivalent to a **90° clockwise rotation**; it will transform (x, y) to (-y, x).
- A **90° counterclockwise rotation about the origin** will take a point (x, y) to (-y, x).
If you provide specific coordinates or a description of the transformation, I can assist further!

To determine the coordinates of \( Y' \) after a 180° counterclockwise rotation about the origin, you can use the rule for 180° rotation, which transforms a point \((x, y)\) to \((-x, -y)\).
The coordinates of point \( Y \) are given as \( (-2, 6) \).
Applying the transformation:
\[
Y' = (-(-2), -(6)) = (2, -6)
\]
So, the coordinates of \( Y' \) are \( (2, -6) \).
The correct response is:
**Y′(2,−6)**.
The coordinates of point \( Y \) are given as \( (-2, 6) \).
Applying the transformation:
\[
Y' = (-(-2), -(6)) = (2, -6)
\]
So, the coordinates of \( Y' \) are \( (2, -6) \).
The correct response is:
**Y′(2,−6)**.

To determine the coordinates of point \( D' \) after a 90° counterclockwise rotation about the origin, you can use the rule for this type of rotation. The transformation takes a point \((x, y)\) to \((-y, x)\).
Since the coordinates of point \( D \) are not provided in your question, I'll demonstrate how to calculate the new coordinates assuming the original coordinates of point \( D \) are \( (x, y) \):
1. Replace \( x \) with \(-y\).
2. Replace \( y \) with \( x\).
Now, let's check each of the options provided to see which could be a valid result:
- For the option \( (8, 4) \):
- If \( D = (4, 8) \): The transformed coordinates would be \((-8, 4)\).
- For the option \( (-8, 4) \):
- If \( D = (4, -8) \): The transformed coordinates would be \( (8, -4)\).
- For the option \( (4, -8) \):
- If \( D = (-8, 4) \): The transformed coordinates would not match \( D' \).
- For the option \( (8, -4) \):
- If \( D = (-4, 8) \): The transformed coordinates would be \( (-8, 4)\).
Without the original coordinate \( D \), we cannot definitively choose the correct answer, but you can use the transformation rule on the original coordinates of point \( D \) to find \( D' \).
If you can provide the original coordinates of point \( D \), I can help to identify which of the options is correct!

To determine the coordinates of \( A' \) after a 270° counterclockwise rotation about the origin, you can use the transformation rule for this type of rotation:
A 270° counterclockwise rotation is equivalent to a 90° clockwise rotation. The transformation takes a point \((x, y)\) to \((y, -x)\).
Since the original coordinates of point \( A \) are not provided in your question, I'll show how to apply the transformation using an example with original coordinates \( (x, y) \):
1. Take \( A = (x, y) \).
2. Transform to \( A' = (y, -x) \).
Now let’s analyze each option provided without knowing the original coordinates of \( A \):
- For the option \( (-1, -2) \):
- Original could be \( (-2, -1) \) → This does not work since \( (-1, -2) \) does not match the transformation.
- For the option \( (1, 2) \):
- Original could be \( (2, -1) \) → This does not work since \( (1, 2) \) does not match the transformation.
- For the option \( (2, -1) \):
- Original could be \( (-1, 2) \) → The transformation would give \( (2, 1) \), also does not work.
- For the option \( (1, 1) \):
- Original could be \( (1, -1) \) → The transformation would give \( (1, -1) \), correct.
Without the specific coordinates of point \( A \), I cannot definitively select the accurate result. However, please apply the rule of \( (y, -x) \) on the original coordinates of \( A \) to determine \( A' \).
If you know the coordinates of \( A \), I can give you a precise answer!
