Graphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?

How to represent inequalities on a number line In order to represent inequalities on a number line: Identify the value (s) that needs to be indicated on the number line. Decide if it needs an open circle or a closed circle; < or > would need an open circle \leq ≤ or \geq ≥ would need a closed circle. To represent inequalities on a number line, we show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle. An open circle shows it does not include the value. A closed circle shows it does include the value. For example, Show x < 3 x < 3 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 ≤

Inequalities in math] are numerical relations that describe where a value lies with respect to some other one. By default, there are four of them: they say whether the first number is: Smaller than (<); Smaller than or equal to (≤); Greater than (>); or Greater than or equal to (≥); the second number.

Solving Inequalities using a Number Line
Explore math with our beautiful, free online graphing calculator. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. A number line helps us to solve an inequality by changing the inequality sign into an equal sign and solving the equation. Though inequalities can be manipulated like equations, the sign becomes reversed when both sides of an inequality are multiplied or divided by a negative number.
Graph the solution of x≥0 on a number line. Solution. First, draw a number line from -5 to 5. The inequality x≥0 is read as "x is greater than or equal to 0.". So, the answer includes zero and all numbers that are greater than 0. Draw a closed circle at 0 to show that 0 is in the solution for this inequality. Solution: In order to represent x < 5 on a number line, we will follow the steps given below. Step 1: Draw a number line, mark 0, and draw equal intervals to the right and left, as shown in the figure given above. Step 2: In the given inequality x < 5, the value of x is less than 5. So, we need to move to the left of 5.

Learn how to manage inequalities on a number line that contains and/ or.I graph them on a number line plus see them on a number line and write the inequality. Inequalities. Directions: In the applet below, you'll see an inequality. 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. If you do this correctly, you'll see a "CORRECT!!!" symbol appear.
