One of the first activities that I created with the help of Linda. We wrote this together in 2009 when I first stumbled across her site and asked her for some help. The activity is based on a section out of Prentice Hall's 2001 ed. of Algebra 2 (Section 3.4). I hope you enjoy the activity below along with the sketch.
