The inequalities of the system are
.
From the graph A, choose a point in the dark blue region, such as
.
To check the solution, substitute the value of
into each original inequality.
Substitute the value of
in the original inequality 1:
.

, This is true.
Substitute the value of
in the original inequality 2:
.
, This is false.
Therefore the ordered pair
is not a solution of
.
From the graph B, choose any point in the dark blue region, such as
.
To check the solution, substitute the value of
into each original inequality.
Substitute the value of
in the original inequality 1:
.


, This is true.
Substitute the value of
in the original inequality 2:
.
, This is false.
Therefore the ordered pair
is not a solution of
.
From the graph C, choose any point in the dark blue region, such as
.
To check the solution, substitute the value of
into each original inequality.
Substitute the value of
in the original inequality 1:
.


, This is true.
Substitute the value of
in the original inequality 2:
.
, This is true.
Therefore the ordered pair
is a solution of
.
The system of the inequalities match with the graph C.
