Updated on June 12, 2015

- Discover the basics of graphing a linear inequality, e.g., the differences among the graphs of
*y*>*ax*+*b*,*y*≥*ax*+*b*,*y*<*ax*+*b*, and*y*≤*ax*+*b* - Use a test point to check if the correct half plane is shaded
- Sketch the graphs of linear inequalities and select a test point to verify the solution set

- Linear inequality
- Half plane

This lesson involves the basics of graphing linear inequalities. As a result, students will:

- Formulate the basic concepts of graphing inequalities.
- Graph systems of inequalities.
