Question
Given a point (9,-3) on a geometric figure, what is the new point when the figure is rotated counterclockwise about the origin 180°?

To rotate a point counterclockwise 180° about the origin, we can use the following formula:
(x', y') = (-x, -y)
So, for the point (9,-3), the new coordinates after rotating 180° counterclockwise about the origin would be:
(x', y') = (-(9), -(-3)) = (-9, 3)
Therefore, the new point is (-9, 3).
(x', y') = (-x, -y)
So, for the point (9,-3), the new coordinates after rotating 180° counterclockwise about the origin would be:
(x', y') = (-(9), -(-3)) = (-9, 3)
Therefore, the new point is (-9, 3).
