Answer:

Option B.

Step-by-step explanation:

The given inequalities are

y

y>x

We need to find the ordered pair which makes both inequalities true.

Check the above inequalities for each given ordered pair.

For (-3,5),

(5) (False)

For (-2,2),

(2) (True)

y>x\Rightarrow 2>-2 (True)

So, both inequalities are true for (-2,2). Option B is correct.

For (-1,-3),

y>x\Rightarrow -3>-1 (False)

For (0,-1),

y>x\Rightarrow -1>0 (False)

Both inequalities are not true for (-3,5), (-1,-3) and (0,-1).

Therefore, the correct option is B.
