The set of all points that satisfy a linear inequality in two variables is called the graph of the inequality.

Work Step by Step

Let us consider the coordinates $\left( x,y \right)$ in an inequality $f\left( x,y \right)$ and check whether they satisfy the inequality. If all the ordered pairs which satisfy the inequality are plotted, then we can obtain the graph of the inequality.
