Answer: (3, -10)

Explanation:

The given inequality :
x - y > 0

Lets check all points to see which point satisfy this inequality.

For (-2, 1) , put x= -2 and y= 1 , we get

-2 - 1 > 0

$\Rightarrow\ -3 > 0$ , which is not true.

For (4, 9) , put x= 4 and y=9 , we get

4-9 > 0

$\Rightarrow\ -5 > 0$ , which is not true.

For (3, -10) , put x= 3 and y=10 , we get

3-(-10) > 0

$\Rightarrow\ 3+10 > 0$

$\Rightarrow\ 13 > 0$ , which is true.

For (3, 3) , put x= 3 and y=3 , we get

3-3 > 0

$\Rightarrow\ -0 > 0$ , which is impossible.

Hence, point (3, -10) satisfies the given inequality x - y > 0 .
