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.

Write the inequality for the graph. So we have to use the sign ≤ or ≥. Either way, there is an infinite number of solutions. Join the points using a dashed line for.

In order to use inequalities on a graph: A graph that shows the total wealth divided by the proportion of people living in the richest and poorest countries since 1970 would be a good indicator of inequality. 332 chapter 8 inequalities the graph of an inequality shows all of the solutions of the inequality on a number line.

How to graph a linear inequality. Rearrange the equation so y is on the left and everything else on the. An open circle is used when a number is not a solution.

You will have to read all the given. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region. The arrow points to the left,.

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. First, graph the equals line, then shade in the correct area. Get ready for 3rd grade;

Now we have to look into the shaded portion. Use the following correspondences between graphs on the number line and absolute value inequalities to write down the correct absolute value inequality given a graph on the number. Write the inequality for the graph shown below.
