# Transformations: Reflection

### by:Folajuwon Samo and Morgan Furness

## Definition and Rule

A transformation that reflects or "flips" , a graph or figure across a line, called the line of reflection.

Rules: If the reflection is through the x-axis then (x,y) equals (x,-y). If the reflection is through the y-axis, (x,y) equals (-x,y). Finally, if the reflection goes through the line, then (x,y) equals (y,x).

## Graph Examples

## Explained Examples

Example 1: Take the coordinates (2,-3) if you were to reflect this point over the X-axis then the new set of cordinates would be, (2,3)

Example 2: Take the coordinates (7,0) if you wish to flip it over the y-axis then the new set of cordinates would be, (-7,0)

Example 3: Take the coordinates (8,2) if you were to reflect over the line then the new set of cordinates would be, (2,8)
