Graphing Inequalities That Include Negative Values

Introduction

Inequalities can include both positive and negative values. Graphing inequalities with negative values on a number line provides a visual way to show...

At a ski resort, a cold-weather warning is issued when the temperature, t, falls below negative 5 degrees Fahrenheit. This means less than negative five, so t <−5.

To graph the inequality, place an open circle at negative 5 because it is not included in the solution. Draw an arrow to the left to represent all values less than negative 5...
