How Can You Graph Inequalities On A Number Line
To solve an inequality using the number line change the inequality sign to an equal sign and solve the equation. In this video you will learn how to graph inequalities on a number line.

In the applet below youll see an inequality.
How can you graph inequalities on a number line. Inequalities can be graphed on a number line. Number lines help make graphing the intersection of two inequalities a breeze. The graph helps you see the values that make the inequality true.
In this case since the inequality symbol is less than. Lets see some examples to understand better. The points on the line.
To do this divide all of the members of the inequality by. This video shows viewers how to graph inequalities on a number line and how to rearrange an inequality if the variable is not on the left side of the inequal. For more practice and to create math worksheets visit Davitily Math Pro.
So any real number greater than or equal to 3 is a solution of the given equation. Y 2x 2 when you create the graph. This first symbol is equal to greater than.
Note that at 2 there is a small empty circle which. 4x - 12 0. Then graph the point on the number line graph it as an open circle if the original inequality was.
Welcome to MooMooMath In this video I would like to talk about inequalities on a number line. We can use the number line to solve inequalities containing and. Sometimes it is impossible to show all the values that make an inequality true.
The inequality is a 16. Inequalities represent a range of values rather than a single value. To begin you must simplify so that you isolate ie.
4x - 12 0. Divide by 4 on both sides. This would mean x can be any value greater than 2 not including 2.
This video shows seven worked-out examples of graphing simple inequalities in one variable on a numberline. The size of the PDF file is 51899 bytes. Preview images of the first and second if there is one.
Before we get started lets look at the inequality symbols. Now this inequality represents all of the numbers between 13 and 32. The focus of this video is not on solving ineq.
Solve the following linear inequality and graph. Graph the inequality as you would a linear equation. Move the BLUE POINT above the number line below and adjust the red and blue sliders off to the top right so that the graph you create is the graph of the inequality shown.
CIVICS You must be at least 18 years old to vote. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. Y 2x 2.
For instance you can have 5 is greater than 4 I remember because this. For example notice that for the graph of x 3 x 3 shown above the end point is 3 3. Let us consider the inequality.
Remember to determine whether the line is solid or dotted. Students can use math worksheets to master a math skill through practice in a study group or for peer tutoring. If you do this correctly youll see a CORRECT.
Add 12 on both sides. The number line should now be divided into 2 regions -- one to the left of the point and one to the right of. At least eliminate any coefficients from it.
However it does include hence getting a closed circle for that value and does not include hence getting an open circle for that value. Write an inequality to describe this situation. This is represented by a line starting from 2 and extending indefinitely marked by an arrow head.
4x - 12 12 0 12. Use the buttons below to print open or download the PDF version of the Graph Basic Inequalities on Number Lines A math worksheet.
