In this unit, systems of linear equalities are explored with two activities and some practice worksheets. In these activities, graphing is done by hand.
The mathematical concept the student should learn from this lesson is how to write a linear inequality. Further, the idea of systems of inequalities and their intersections is introduced.
This activity is an introductory activity to systems of linear inequalities. It begins with a system of linear equations and gradually goes into systems of inequalities by asking students to interpret the meaning of the area above and below the lines.
