When drawing lines it is important to use a dashed line for inequalities using the symbol < or >.

Graphing inequalities symbols. Here are the steps to graphing a linear inequality. You must know and recognize these. To graph a linear inequality:

− 4 ≤ x ≤ 4. Step 1 replace the inequality symbol with an equal sign and graph the resulting line. Remember to determine whether the line is solid or dotted.

We use an open dot, \circ, ∘, to represent < < and >. The first thing is to make sure that variable y y is by itself on the left side of the inequality symbol, which is the case in this. To graph this type of inequality, both the maximum and minimum are found on the number line and a circle is drawn at those points.

Inequalities on a graph allow us to visualise the regions that satisfy one or more inequalities. Linear inequalities are the expressions where any two values are compared by the inequality symbols such as, ‘<’, ‘>’, ‘≤’ or ‘≥’. Always start by isolating the variable \color {red}y y on the left side of the inequality.

Graph the inequality as you would a linear equation. Draw a number line on the whiteboard and start with simple examples of graphs of inequalities on a number line, such as x < 0, x > 0, x ≤ 0, and x ≥ 0. < “l” less than > greater than ≤ less than or equal to (2 symbols together) ≥ greater.

Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it. We can graph inequalities with one variable on a number line. How to graph a linear inequality.
