Graphs of Linear Inequalities with Sliders

Summary

• In this tutorial, you’ll explore the graphs of Linear Inequalities using sliders. The steps in the tutorial include:– Creating a Graph Window.– Configuring two sliders. – Linking the sliders to a Linear Inequality in slope-

intercept form.– Manipulating the Sliders.

Create a Graph Window

Click on the + tool to activate this menu.

Create the First Slider

By default the keyboard is active. Click on the Keyboard button to deactivate it.

Create the First Slider

Click on Menu. Select Actions > Insert Slider.

Configure the First Slider

This slider is for m in the slope-intercept form. Configure as shown. Press OK.

Move the Slider

Press and hold the Slider to bring up the option for moving it. Select Move and reposition the slider.

Move the Slider

Position the Slider as shown.

Create the Second Slider

Click on Menu. Create the second Slider.

Configure the Second Slider

This slider is for b in the slope-intercept form. Configure it as shown. Click OK.

Move the Slider

Repeat with the second Slider and place both in the area shown above.

Input the Slope-Intercept Form

Activate the Function Entry Line by clicking on + in the upper-right-hand corner. Press the Delete key and

input the inequality shown. Press Enter.

Input the Slope-Intercept Form

The graph shown uses the values for m and b in the sliders.

Manipulate the Sliders

Change the values on the sliders by sliding the arrows at the bottom of each Slider. The graph will update.
