Classifying Project Feasibility Models

You are assisting a project manager in evaluating two different resource-allocation models for a new contract. After graphing the systems of equations for both models, you observe the following:

  1. In Model A, the lines intersect at a single coordinate, representing a unique solution.
  2. In Model B, the lines are coincident, meaning they lie directly on top of each other and share every point as a solution.

Identify the single mathematical term used to classify both Model A and Model B. State the definition of this term regarding the number of solutions required.
