Song about GRAPHING LINEAR INEQUALITIES IN 2 VARIABLES. Includes lyrics, animation, and music. From SkitSoPhrenia and I Feel A Song Coming On by Cindy Boyd. DIFFERENT FROM OTHER SONG ON THIS SITE. I use to reinforce and reteach what I have taught. No vocals at this time. I use smilies whenever possible because all my students identify with them as they have no characteristics that denote race.
