In Class Work #1: Pg. 576: 3-14, minutes then you will turn it in then we are moving on to reflection.

TRANSFORMATIONCOORDINATE RULEEXAMPLE Translation (shift)

REFLECTION across the x-axis: Reflection across the x-axis so the x-axis is the mirror 5 5 The distances from the mirror to each point is equal!
