Ordered pair is
<u>Step-by-step explanation:</u>
We have the following inequalities:
and . In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and , which implies:
⇒
⇒
⇒
putting value of x in both inequalities we get,
and
and
and
Hence at x = and y = above inequalities are satisfied. ∴ Ordered pair is
