<em>A linear inequality in two variables takes the form:</em>
<em>y>m x+b or y<m x+b. ( where x and y are two variables)</em>
Linear inequalities are closely related to graphs of straight lines; recall that a straight line has the equation y=m x+b.
The solution to a linear inequality includes all the points in one half of the plane. We can tell which half by looking at the inequality sign:
> The solution set is the half plane above the line.
≥ The solution set is the half plane above the line and also all the points on the line.
< The solution set is the half plane below the line.
≤ The solution set is the half plane below the line and also all the points on the line.
"We use dotted line for a strict inequality and solid line for an inequality sign which also include equality" .
