Front

What is the difference between a closed dot and an open dot on a number line?

Back

A closed dot indicates that the number is included in the solution (≤ or ≥), while an open dot indicates that the number is not included ( < or >).

Front

What is the first step in solving a two-step inequality?

Front

How can you check if your solution to an inequality is correct?

Back

Substitute a value from the solution set back into the original inequality to see if it holds true.
