Question

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

O No, because ( - 1, 2) is a solution to only one of these inequalities.
O Yes, because ( – 1, 2) is a solution to both inequalities.
O Yes, because ( - 1, 2) is the point of intersection of the two boundary lines of this system.
No, because ( – 1, 2) is not a solution to either inequality.

Answer 1

Yes, because (-1,2) is a solution to both inequalities

Explanation:

2>-1 so the first inequality is correct

-1+2>0 so the second inequality is correct
