Once inequalities are solved (click
here to go to a In the inequality x < 4, "x" could be any number less than 4. This not only includes integers, but decimals and fractions, too. We can graph the solution set on a number line.
Let's graph the solution set for the inequality x ≥ 1.
If the symbol in the inequality is < or >, use an open circle above the number being graphed. If the symbol in the inequality is ≤ or ≥, use a closed circle above the number being graphed. If the symbol in the inequality is < or ≤, draw an arrow to the left to show "less than". If the symbol
in the inequality is > or ≥, draw an arrow
to the right to show "greater than". Let's practice graphing inequalities.
