# Writing the Line of Reflection

## Exploring Reflections

Look at the reflection below.
1. What is the line of reflection?
2. What do you notice about the distance A is from the axis and the distance A' is from the axis? Is this the same for the other points?
3. What do you notice about the coordinates of the preimage and the image?
Move the point (0, -2) from the line of reflection to (2, 0).
