2. 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:
y > mx
y > mx + b
y £ mx
y £ mx + b
3. Create a Graph Window
Click on the +tool to activate this menu.
7. 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.
10. Edit the Inequality
Now change the inequality to the one shown above.
Press Enter. A greater slope value leads to a steeper
graph.
y £ 3x
11. Edit the Inequality
Now change the inequality to the one shown above.
Press Enter. Note how the y-intercept displaces the
graph vertically.
y ³ x +1
12. Edit the Inequality
Now change the inequality to the one shown above.
Press Enter. Note how the y-intercept displaces the
graph vertically.
y £ x -1
13. Graph a Second Inequality
Now change the Inequality to the one shown above. In
addition, graph a second inequality.
y < -3x + 2
y > 2x +1
