Is (-1,2) a solution of the system y> x and x+y> 0?

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.

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant
