What does an open dot on a number line indicate about the value?

Back

The value is not included in the solution set.

Front

What does a closed dot on a number line indicate about the value?

Back

The value is included in the solution set.

If x > 3, how would you represent this on a number line?

Back

Open dot at 3, line extending to the right.

What is the difference between < and ≤ in graphing inequalities?

Back

< uses an open dot; ≤ uses a closed dot.
