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.
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".
