13 Μαΐ 2024 · Graph the inequality x > -1 on the number line. Solution: Here, x> -1 represents ‘x is greater than -1,’ whose graph is plotted, and the open circle denotes that -1 is not a solution. Graph the inequality x ≥ -3. Solution: Here, x ≥ -3 represents ‘x is greater than or equal to -3,’ thus, the value -3 is included.
Correct answer: x <−4 or x ≥ 2. Explanation: An open circle indictes "less than" or "greater than," while a closed circle indicates "greater than or equal to" or "less than or equal to". This number line includes values that are less than −4 or greater than or equal to 2.
We can use the number line to solve inequalities containing <, ≤, >, and ≥. To solve an inequality using the number line, change the inequality sign to an equal sign, and solve the equation. Then graph the point on the number line (graph it as an open circle if the original inequality was "<" or ">").
