-----> is not true
therefore
the ordered pair is not a solution
case b) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case c) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
