Graphing a Linear Inequality

Open a new graphing window.

The blinking cursor is on the function entry line.

Change the equals sign to an inequality sign,

then input the inequality and press Enter.

Notice that the shaded region corresponds to the inequality.

In this case y > x means the region above the line is shaded.

Input an inequality with a negative coefficient.

Notice how this graph is shaded below the line.

Edit the inequalities by pressing the up arrow

and editing the inequality.
