Draw a number line. A number line is a straight horizontal line on a page with a series of vertical lines to represent figures. When graphing integers, the figures on the line should be whole numbers. These numbers can be negative numbers, as well as positive.
Read the inequality equation. An inequality equation looks like "x < 5." This reads as "x is less than 5." If the symbol were reversed -- "x > 5" -- then the equation would read "x is greater than 5."
Look at the domain that is included with the equation. The domain represents the various numbers that you can use to solve the inequality equation. It's represented by something like "D = {Integers}" or "D = {Positive Integers}."
Graph the integers to solve the inequality equation based on the domain you are provided. For example, if the inequality equation reads "x < 5" and "D = {Integers}, you would add a filled-in circle over all the numbers on the line graph that are less than 5, meaning you would start with 4. Add an arrow pointing toward the left to show that all numbers to the left of 5 are less than 5.
