Air traffic controllers are in charge of planes taking off and landing in their airport and any others that fly overhead o the way to other destinations. When planes come into their airspace, they track them using coordinate systems.
Plane A is at (12,5) flying towards (21,12). Plane B is moving from (9,8) to (16,12).
Is there a need to course correct?

When an object is placed in front of a plane mirror, the reflection appears to be at a distance equal to that of the object from the mirror.
The coordinates of the object (2,3) and the mirror (4,9) are plotted on a graph sheet. Predict where the coordinates of the reflection would have been if it could be plotted.
What is the distance between the object and the reflection?
Verify that it is twice the distance of the object from the mirror.
