Graphical Solution of Linear Inequalities

GeoGebra Dynamic Worksheet
Step 1. Plot the line of the linear inequality treating it as linear equation. You will get a
 straight line. The line can be dotted ( in case of strict inequality involving < or >
 symbol) or it can be a solid line (involving >= or <= symbol).

Step 2. Take a test point , (the origin is the most convenient unless the line of the
inequality falls on it), and plug it into the same linear inequality. If the test point makes
the inequality true, then shade that side of the line. If the test point makes the inequality
false, then shade the opposite side of the line.
Enter a new inequality in the text field.

  1. Inequalities plays an important role in the research mathematics.It provides a solution of the equations which are not in equality situation.Like
    2x> 3.
    Its am inequality.
