What is the rule for the reflection?

A reflection is an example of a transformation that takes a shape (called the pre-image) and flips it across a line (called the line of reflection) to create a new shape (called the image).

The most common lines of reflection are the x-axis, the y-axis, or the lines y=x or y=−x.

The x-axis,

Reflection across the x-axis: (3,2)→(3,−2)

i.e. for reflection across the x-axis the x-coordinate remains same and y-coordinate change to negative sign.

The y-axis

Reflection across the y-axis: (3,2)→(-3,2)

i.e. for reflection across the y-axis the y-coordinate remains same and x-coordinate change to negative sign.

The line y=x

Reflection across the line y=x: (3,2)→(2,3)

For reflection across y=x the x and y value get interchanged.

The line y=−x.

Reflection across the line y=−x: (3,2)→(−2,−3)

For reflection across y=-x the x and y value get interchanged with opposite signs.
