we will proceed to resolve each case to determine the solution 
we have


we know that
If an ordered pair is the solution of the inequality, then it must satisfy the inequality.
<u>case a)</u> 
Substitute the value of x and y in the inequality

 ------> is True
 ------> is True
therefore
the ordered pair  is a solution of the inequality
 is a solution of the inequality
<u>case b)</u> 
Substitute the value of x and y in the inequality

 ------> is False
 ------> is False
therefore
the ordered pair  is not a solution of the inequality
 is not a solution of the inequality
<u>case c)</u> 
Substitute the value of x and y in the inequality

 ------> is True
 ------> is True
therefore
the ordered pair is a solution of the inequality
 is a solution of the inequality
<u>case d)</u> 
Substitute the value of x and y in the inequality

 ------> is True
 ------> is True
therefore
the ordered pair  is a solution of the inequality
 is a solution of the inequality
<u>case e)</u> 
Substitute the value of x and y in the inequality

 ------> is False
 ------> is False
therefore
the ordered pair  is not a solution of the inequality
 is not a solution of the inequality
<u>Verify</u>
using a graphing tool
see the attached figure
the solution is the shaded  area above the line
The points A,C, and D lies on the shaded area, therefore the ordered pairs A,C, and D are solution of the inequality
