#(-1, -1)# is a solution to #y>x-2#.

#(1, -1)# is not a solution.

Substitute the values into the inequality.

First Possible Solution

#(-1, -1)#

#y>x-2# =

#-1> -1-2# =

#-1> -3#

This is a correct statement.

#(-1, -1)# is a solution for this inequality.

Second Possible Solution

#(1, -1)#

#y>x-2#

#-1>1-2#

#-1> -1#

This is an incorrect statement. #-1=-1#

#(1, -1)# is not a solution for this inequality.
