Question

Given the system

y > -2

x + y < 4

Answer 1

1. Points that lie on the intersection area of the inequalities are solutions.

For example (0,2), (-4,4), (2,-1), (-8,0) and all others which lie in this area.

2 Not solutions are points that are on the lines (because we have signs > and <, not ≤ and ≥), or on the areas that are not intercepted. For example, (6,2), (2,2), (2,-4),(-6,-2).
