Solve the following system of inequalities graphically:
Q4.
Graphical representation of is given in the graph below.
For ,
The solution to this inequality is region above line including points on this line because points on the line also satisfy the inequality.
For ,
The solution to this inequality is half plane corresponding to the line containing point excluding points on this line because points on the line does not satisfy the inequality.
Hence, the solution to these linear inequalities is the shaded region as shown in figure including points on line and excluding points on the line.
This can be represented as follows:
