How Do You Graph a Great Than Inequality on the Coordinate Plane?
Do you know how to graph a linear equation? If you do then graphing an inequality will not be a problem for you. There are a couple of differences: is the line solid or dashed, and which half plane do you have to shade. Watch this video...
