The simplest way to solve this is to plug in each of your given ordered pairs into the inequality and see if it turns out to be true. For example if you use (-2,-2) you would have the equation -2+2 < -2 and then 0 < -2 which is incorrect so you know that is not the right answer. (2,-1) is the correct ordered pair because when you plug in the values you will get -1+2<2 and then 1<2 which is correct.
