$(-1, -1)$ is a solution to $y>x-2$ .

$(1, -1)$ is not a solution.

Substitute the values into the inequality.

First Possible Solution

$(-1, -1)$

$y>x-2$ =

$-1> -1-2$ =

$-1> -3$

This is a correct statement.

$(-1, -1)$ is a solution for this inequality.

Second Possible Solution

$(1, -1)$

$y>x-2$

$-1>1-2$

$-1> -1$

This is an incorrect statement. $-1=-1$

$(1, -1)$ is not a solution for this inequality.
