How do you use a number line to represent an inequality? x > 4 or x ≤ -9
In this lesson you will learn how to represent the solution set of an inequality by creating a number line.
A variable is a letter or symbol that represents an unknown number or set of numbers. For example, x or ★ could be used to represent unknown numbers. An inequality has more than 1 solution.
represents: An open circle > greater than < less than represents: A closed circle ≥greater than or equal to ≤ less than or equal to
Using the incorrect circle to represent the inequality symbol. Remember: ≥, ≤ >, < closed circle open circle
Create a number line to represent the solution set of x > 2. • Write it in words. 2. Identify the type of circle needed. 3. Identify the shading.
Create a number line to represent the solution set of x > 2. • X is greater than 2. 2. Open Circle because x ≠ 2. 3. Shade values greater than 2.
Create a number line to represent the solution set of x > 2. The shaded portion includes all numbers greater than 2!
In this lesson you have learned how to represent the solution set of an inequality by creating a number line.
Create a number line to represent the solution set of x ≤-4.
Given an inequality on a number line, identify five values that are in the solution set and five values that are not in the solution set.
Create a number line to represent the solution set of x ≤-15.
