Please look in your text book for this problem Statement

The inequalities of the system are .

Observe the graph, the dark blue shaded region indicates the solution of the system of the inequalities and the two dashed lines are not solutions of the system of the inequalities because these represent the symbols are .

From the graph, 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 statement.

Substitute the value of in the original inequality 2: .

, This is false statement.

Therefore the ordered pair is not a solution of .
