What are Linear Inequalities?
Linear inequalities involve a linear function with symbols less than (<), greater than (>),
less than or equal to (≤) and greater than or equal to (≥).
Linear inequalities can be of any dimension. In this unit we are studying linear inequalities in one and two variables.
Two dimensional linear inequalities are expressed in two variables, namely x and y, which divides the entire plane in two parts.
The two dimensional planes are basically divided in upper half and lower half plane or left half plane and right half plane.
The inequalities are very useful for problem solving in science, mathematics, statistics, engineering, etc.
A linear programming is the advanced study of linear inequalities, where function is called Optimal Function
and we find the minimum and maximum values.
