Hey there!

To figure out whether or not this is a solution, plug the point pair into the system and see whether it holds true for both inequalities.

2 > -1 <-- this is true since 2 is in fact greater than -1

-1 + 2 > 0

1 > 0 <-- this is true since 1 is in fact greater than 0.

In conclusion, (-1,2) is a solution since it holds true for both inequalities.
