Aim#4 Reflections

How Do we Graph Transformations that are Reflections ?

-A reflection; is a transformation that creates figures that are mirrored images of the original.

Examples of Reflections ;

      

- typically , if you are not given or asked to graph a reflection directly , you can still show reflection through your coordinates;

 - To reflect in the x-axis (x,y) -> ( x,-y)

 - To reflect in the y-axis (x,y) -> ( -x,y)

For example: What are the coordinates of the points ( 4,6) reflected in the y- axis ?

                       y- axis ( x,y) -> (-x,y)  Answer : ( -4,6)
