Answer
Inequality symbols like $,\le,\ge $ are used to express the inequality between $ x $ and $ y $.
Work Step by Step
A system of linear inequalities in two variables $ x $ and $ y $ are the equations which will use the various inequality symbols like $,\le,\ge $ to represent the relation between $ x $ and $ y $.
In the linear inequality, the power of variables $ x $ and $ y $ is always one.
Some examples of linear inequalities are shown below:
$\begin{align}
& 3x-6y\ge 20 \\
& x+2y\le 5 \\
& x<0 \\
\end{align}$
Hence, the inequality symbols $,\le,\ge $ are used to express linear inequalities in two variables $ x $ and $ y $.
