What are the different types of inequalities and how are they graphed?

Accepted Answer

Greater than, or less than (> or <) are graphed with open circles (meaning the number is not part of the solution).    
Greater than or equal to, less than or equal to (≥or ≤) are graphed with closed or shaded circles (meaning the number is included in the solution).
