Protocol for Interpreting Graphical Boundary Constraints

As a technical documentation specialist, you are writing a guide on how to convert visual graphs into mathematical inequalities for the operations team. For a graph with a boundary line defined by the equation y=2x−1y = 2x - 1, state the rule for how a solid boundary line affects the choice of the inequality symbol. Furthermore, describe the standard role and purpose of using a test point (such as the origin) in the process of identifying the correct solution region.
