This is a Powerpoint lesson that I use to teach Section 6.6 of the Prentice Hall Algebra 1 textbook. It can also be used as a review in Algebra 2 classes. The presentation can be edited to make it perfect for your specific classes.
It includes a video that explains the topic which makes it perfect for new teachers, home teachers, or on days that you can't be in the classroom. (I use that time to take roll.)
