# Chapter 6 - Linear Inequalities

In previous classes, you have learnt about equations in one and two variables. You also learnt how to convert statement problems in the form of equations. In this chapter, you’ll study linear inequalities in one and two variables. What is a linear inequality? Inequalities are a part and parcel when you’re working on algebra problems. A linear inequality is an inequality that consists of a linear function. It represents the data which is not equal in the graph form. A linear inequality is like a linear equation; the only difference is that the equality sign is replaced by the inequality sign.

A good understanding of linear inequalities is important, as linear inequalities have quite a few real-life applications, especially in the field of mathematics, science, psychology, economics and more.

## Let’s take a look at topics and sub-topics of Class 11 Maths Chapter 6, Linear Inequalities
