How To Write An Inequality From A Number Line
The open circle above a number means it is not included as part of the solution to the inequality while the solid circle means that it is. We just put a little dot where the 3 is right.

Inequalities can be represented on a number line.
How to write an inequality from a number line. Number lines example 1. In this example we will look at how to show the solution to an inequality on a number line. Inequalities can be represented on a number line as shown in the inequalities below.
Use a solid dot for. Inequalities on a number line. From the given graph on the number line since the arrow is towards left and there is an open circle it is a less than inequality.
Use a hollow dot for. D x 20. C x 20.
From the given graph on the number line since the arrow is towards left and there is a closed circle it is less than or equal to inequality. Since it is starting from 20 with a closed circle the inequality is x 20. Graphing an inequality on a number line is very similar to graphing a number.
Number lines help make graphing the intersection of two inequalities a breeze. Alternatively you can determine inequalities from number lines. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection.
So number lines can be drawn from mathematical inequalities. For instance look at the top number line x 3. The most important thing to remember when.
Since it is starting from 190 with an open circle the inequality is x 190.
