The image of the point (1, -2) after a rotation of 180° about the origin is:

Step-by-step explanation:

We have been coordinates of a point . We are asked to find the coordinates of the point after a rotation of 180° about the origin.

We know that after rotating a point 180° about the origin, the coordinates of point changes their signs to opposite. The rule of rotating a point 180° about the origin is .

After rotating the point 180° about the origin its coordinates would be:

Therefore, the coordinates of the given point after a rotation of 180° about the origin would be .

1. minimum

2. 6400

3. eight
