3. Solving Linear Inequalities in two variables
Coordinate Plane

4. Half plane
A region containing all points that has one boundary, which is a straight line that continues in both directions infinitely.

5. Steps for Graphing Inequalities
Get in slope-intercept form
Determine solid or dashed line
Determine whether to shade above or shade below the line (Test Points)
If the test point is true, shade the half plane containing it.
If the test point is false, shade the half plane that does NOT contain the point.
