To find the coordinates of the image \( Y' \) after a 180° counterclockwise rotation about the origin, we can use the following transformation:
For a point \( (x, y) \), a 180° rotation about the origin transforms it to \( (-x, -y) \).
The coordinates of point \( Y \) are \( (-2, 6) \).
After applying the transformation:
\[ Y' = (-(-2), -6) = (2, -6) \]
Thus, the coordinates of \( Y' \) are \( (2, -6) \).
Therefore, the correct response is:
Y′(2,−6).
