Graphs of Linear Inequalities
Summary
• In this tutorial, you’ll explore the graphs of Linear Inequalities. The steps in the tutorial include:– Creating a Graph Window.– Graphing Linear Inequalities:
Create a Graph Window
Click on the + tool to activate this menu.
Input the Inequality
Press the Delete key to remove the equals sign. A menu of Inequalities comes up.
Input the Inequality
Input the inequality shown. Press Enter.
Graph the Inequality
This is the basic graph of a Linear Inequality.
Edit the Inequality
Click on the + sign at the upper right to bring up the Function Entry line. Then press the up arrow. You’ll see the
inequality.
Click here.
Then Click here.
Edit the Inequality
Change the inequality to the one shown above. Then press Enter.
Edit the Inequality
Note the change in the graph of the inequality.
Edit the Inequality
Now change the inequality to the one shown above. Press Enter. A greater slope value leads to a steeper
graph.
Edit the Inequality
Now change the inequality to the one shown above. Press Enter. Note how the y-intercept displaces the graph
vertically.
Edit the Inequality
Now change the inequality to the one shown above. Press Enter. Note how the y-intercept displaces the
graph vertically.
Graph a Second Inequality
Now change the Inequality to the one shown above. In addition, graph a second inequality.
