Graphing

One Variable

When graphing inequalities on a number line use the appropriate notation. A closed circle indicates that the point is included in the solution set and an open circle indicates that the point is not part of the solution set.

Example

Graph x > 2

Step 1. Draw the number line.

Graph-ex1-1

Step 2. Find the value and mark it with the appropriate notation. An open dot indicates that the point x = 2 is not included in the solution.

Step 3. Shade everything to the right, showing "greater than".
