To show the feasible region, follow these steps:
Example:
Shade the feasible region for the following inequalities:

\(y<= -1/2X +4\)

\(y>X - 2\)

\(X >= -4\)

1.    Select the Inequality Graphing App icon .

2.    Press any key.
Note: see the Introduction for information how to change the style and color of inequality.

3.    Input \(y<= -1/2X +4\) into Y1 and the other two inequalities in Y2 and Y3.

4.    Press the c key to toggle the entry to x= form.

5.    Press the left arrow key ‹ on X1 and change the line and color style as appropriate.

6.    Input x>=1 into X1

7.    Press h to show all the relations.

8.    Press a à and press the right arrow key › to the Inequality menu.

9.    Select option 2 for "Inequal Intersection" and press =.
