Describing Constraint Intersections in Operational Planning

An operations analyst is documenting the graphical constraints for a resource allocation model represented by the system:

{4x+3y≥12y<−43x+1\begin{cases} 4x + 3y \geq 12 y < -\frac{4}{3}x + 1 \end{cases}

Identify the specific graphical features of this system by describing:

  1. Which inequality uses a solid boundary line and which uses a dashed line.
  2. The geometric relationship between the two boundary lines (e.g., are they perpendicular, parallel, or intersecting?).
  3. The final conclusion regarding the existence of a common solution region for this specific system.
