Graph Inequality on a Number line-lesson, examples and interactive inequality graph maker.
When we are looking at inequalities on a number line, we use open and closed circles to represent the values: for greater than (>) and less than (<) we use open circles to show that the value itself is not included. for greater than or equal to (≥) and less than or equal to (≤) we use closed circles to show that the value itself is included.

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.
18 Ιαν 2024 · Welcome to Omni's graphing inequalities on a number line calculator, where we'll take on some linear inequalities and see how to plot them on the number line. And once we see how to deal with one, we'll add some more to the pile and get to graphing systems of inequalities.
15 Σεπ 2021 · All values that lie to the right of \(3\) on the number line are greater than \(3\). The number \(3\) itself is not greater than \(3\). A graph quickly conveys the solution set. To visually denote that \(3\) is not greater than \(3\), we will use an open circled; a circle that is not filled.
