With the greatest of enthusiasm, I share my most recent power point with you on "Graphing Inequalities in Two Variables".
* The lesson begins with a review showing ordered pairs as solutions to inequalities.
* Step by step, students move into graphing inequalities of vertical and horizontal lines.
* They review the meaning of boundaries, half-planes, and how to test for the solution half-plane.
* Progressing, they graph inequalities in two variables using slope-intercept
