Linear Inequalities

Have you ever been to an amusement park? If you have, you must have often seen that every ride has a height limit indicated by a less than or a greater than height value. This is nothing but inequality. Inequalities are not only used in mathematics but also in science, statistics, optimisation problems, economics, psychology, etc. In this chapter, we will learn about inequalities in one variable, two variables, graphing such inequalities, and finding solutions to systems of linear inequalities.
