Graph of Linear Inequalities in two Variables

Content

Inequalities involving two Variables are generally solved by the graphical method.

To solve linear inequalities of two variables, you first construct the table of value for the graph.

Recall from the table of Linear Equations

If we have a Linear Equation X + Y = 3, where the table is drawn as

Firstly make Y subject of…
