y < 2x + 5
y > -x
Using point (2, 2):
2 < 2(2) + 5 = 4 + 5 = 9 ==> true
2 > -2 ==> true
so this poit represents a solution
Using point (-3,1)
1 < 2(-3) + 5 = -6 + 5 = -1 ==> false
so this poit DOES NOT represents a solution
Using point (0,2)
2 < 2(0) + 5 = 5 ==> true
2 > -0 = 0 ==> true
so this poit represents a solution
Using Point (0,7)
7 < 2(0) + 5 = 5 ==> false
so this poit DOES NOT represents a solution
