Difference between a closed circle or an open circle when graphing an inequality

Double points if you also explain the difference between an inequality and an equation, not just the symbol

Closed circle represents inclusion such as greater than or equal to or less than or equal to


Open circle represents non-inclusion such as less than or greater than but not equal to 


A CLOSED circle means that value is part of the solution set

Double points: An standard equation has one solution while an inequality has a solution SET
