Solve the following system of inequalities graphically:
Q1.
Graphical representation of and is given in the graph below.
The line and divides plot in four regions i.e.I,II,III,IV.
For ,
The solution to this inequality is region II and III including points on this line because points on the line also satisfy the inequality.
For ,
The solution to this inequality is region IV and III including points on this line because points on the line also satisfy the inequality.
Hence, solution to is common region of graph i.e. region III.
Thus, solution of is region III.
This can be represented as follows:
The below green colour represents the solution
