Example:
Graph the solution set of the system of linear inequalities
Solution:
We have
The corresponding equations of inequalities (A) and (B)


For x – intercept 
For x – intercept 
Put in (1) we get 
Put in (2) we get 








For y – intercept 
For y – intercept 
Put in (1) we get 
Put in (2) we get 








Test 
Test
