Graph Inequality on a Number line-lesson, examples and interactive inequality graph maker.
This free guide to graphing inequalities on a number line will teach you how to graph solutions to inequalities on a number line. The guide includes key definitions, examples, and practice problems to help you to understand how to easily and accurately graph an inequality on a number line.
To show an inequality on a number line with just one value, follow these steps: find the value that you are going to need. represent the value with either an open or closed circle (see below) draw a line from the circle to the left end of the number line if the symbol is < or ≤.
The graphing inequalities on a number line calculator allows up to three inequalities on one picture, and even returns what numbers satisfy all of them.

Like we plot real numbers, we can also graph inequalities on a number line. It helps us find and represent the entire region covered by inequality. While plotting equality, for example, x = 5, we draw a circle over the number (here, 5) on the number line.
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 ">").
How Do You Graph an Inequality on a Number Line? Graphing x = a. Before we graph an inequality on a number line, let's look at how to graph an expression with an equals sign. If you had to graph x = 2, that means that x must be exactly equal to 2. It cannot be any other number except for 2.
How to graph inequalities on a number line. In previous lessons we looked at how to graph points and lines in the ???xy???-plane along two axes: the horizontal ???x???-axis and the vertical ???y???-axis. In this lesson we’re talking about graphing inequalities, which will be done on a number line.
