To graph inequality, Graph every linear inequality in the same xy-axis and Isolate the y variable to the left of inequality.


If the symbols are > and ≥, we shade the area above the boundary line using dashed and solid lines, respectively.

On the other hand, if the symbols are < and ≤, we shade the area below the boundary line using dashed and solid lines, respectively.

Shade the region where all the areas of the linear inequalities intersect or overlap. If there is no region of intersection, we say that the system has no solution.



The intersection of graphs will give the solution.


This below example will clarify how to graph inequalities.


The blue color region is the solution of the inequality
