What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

How do you graph an inequality on a number line?

Back

To graph an inequality, use an open circle for < or > and a closed circle for ≤ or ≥. Shade the region that represents the solution set.
