This is a set of notes. Not only do you get a file (in both PDF and Promethean formats) to display to students, but you also get a file to print for guided notes. This is one of my secrets to getting students to take notes well. The problems are already printed, so they don't have to waste time copying, particularly with word problems.
These notes cover the following topics:
*slope / rate of change
*parallel and perpendicular lines
