Take each answer choice, one at a time, and plug them into each inequality
jimthompson5910 (jim_thompson5910):
Checking choice A
x + y > 2
3 + (-1) > 2
3 - 1 > 2
2 > 2
Since that last inequality is false, (3,-1) does NOT work
jimthompson5910 (jim_thompson5910):
So choice A is NOT the answer
OpenStudy (anonymous):
ok
jimthompson5910 (jim_thompson5910):
do the same with the other answer choices and rule out any choices you can
remember, the ordered pair has to work with BOTH inequalities
