QUESTION 1
The given inequality is  
 and
 and  .
.
If (3,-2) is a solution; then it must satisfy both inequalities.
We put x=3 and y=-2 in to both inequalities.
 and
 and  .
.
 :True and
:True and  :True
:True
Both inequalities are satisfied, hence (3,-2) is a solution to the given system of inequality.
QUESTION 2

We put x=1 and y=4 in to both inequalities.
 and
 and  .
.
 :True and
:True and  :True
:True
Both inequalities are satisfied, hence (1,4) is a solution to the given system of inequality.
Ans: True
QUESTION 3
The given inequality is  
 and
 and  .
.
If (0,-2) is a solution; then it must satisfy both inequalities.
We put x=0 and y=-2 in to both inequalities.
 and
 and  .
.
 :False and
:False and  :False
:False
Both inequalities are not satisfied, hence (0,-2) is a solution to the given system of inequality.
Ans:False
