Answer:
Step-by-step explanation:
for it to be a solution, it has to satisfy both inequalities....not just one
y > x.......(-1,2)....x = -1 and y = 2....now we sub
2 > -1.....2 is greater then -1......this is true
x + y > 0....(-1,2)...x = -1 and y = 2.....sub
-1 + 2 > 0
1 > 0......1 is greater then 0....this is true
so (-1,2) IS a solution to this system because it satisfies both inequalities
