Algebraic Representations Of Reflections
To reflect over a vertical line, such as $x=a$, first translate so the line is shifted to the yaxis, then reflect over it, then translate back so the line is shifted to its original position $$(x,y)\mapsto (xa,y) \mapsto (ax,y) \mapsto (2ax,y)$$ On this lesson, you will learn how to perform reflections over the xaxis and reflections over the yaxis (also known as across the xaxis and across the ya
