Question Analysis
This question focuses on identifying the geometric shape formed by a bounded solution region.

Key Concept Explanation
The solution region is bounded if enclosed by intersecting lines.
The vertices are the points where boundary lines intersect.
Common shapes: triangles (3 vertices), quadrilaterals (4 vertices).

Step-by-Step Solution
1. Graph the inequalities:
y = x + 2 (solid line, shaded below).
y = -x (solid line, shaded above).
y = 4 (solid ho...
