pick one point at the shaded area like (-1,0) and check which system of inequalities is true
For the first option 0 > 1 is not true
The first option is wrong
for the second option:
0 <= 1
y - x = 0 - (-1) = 1 > 0
the second option is true
the third option
0 <= 1
y - x = 0 - (-1) = 1 < 0 this is not true
the third opt
