This is an Algebra lesson for the SmartBoard on solving a system of linear equations by graphing. This Notebook file starts with a warm-up problem which is later revisited in the lesson. The need to learn a method of solving a system is established, and the method of solving by graphing is discovered. This is followed by numerous examples of solving a system, which include activities for kinesthetic learners so they can more easily make connections. Special systems are also discussed and there are several real-world application problems. The lesson ends with a wrap-up activity summarizing the new concepts.
