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 degrees?(1 point)

Answer 1

When a point is rotated counterclockwise about the origin 180 degrees, its x-coordinate and y-coordinate switch signs.

So the new point, when the figure is rotated counterclockwise about the origin 180 degrees, is (-9, 3).
