What do the symbols ≤ and ≥ represent when graphing inequalities?

Back

They represent a 'closed dot' on the number line, indicating that the value is included in the solution.

Front

What do the symbols < and > represent when graphing inequalities?

Back

They represent an 'open dot' on the number line, indicating that the value is not included in the solution.
