Question

what is the correct transformation rule for rotating a point 180 degrees around the origin? a. add the coordinates b. change the sign of the new y - coordinate c. change both coordinates to their opposites d. swap the coordinates

Explanation:

When rotating a point 180 degrees around the origin in a coordinate - plane, if the original point has coordinates (x, y), the new point after rotation has coordinates (-x, -y). This means both the x - coordinate and the y - coordinate are changed to their opposites.

Answer:

c. Change both coordinates to their opposites
