Recalling Boundary Line Styles and Test Point Rules for Linear Inequalities
You are documenting a workflow for your operations team to help them interpret resource constraint graphs. One of the graphs is bounded by the solid boundary line ${}3x - y = 6$, where the shaded region represents the feasible solution set.
To ensure your team can correctly deduce the inequality from the graph, write an explanation that addresses the following points:
- Explain what a solid boundary line indicates about the inequality symbols to be used.
- If you choose the origin (0, 0) as a test point and it lies in the unshaded region, state whether substituting its coordinates into the correct inequality must yield a true or a false statement.
- Show the evaluation of the expression
${}3x - y$at the origin (0, 0) and explain how this confirms that${}3x - y \geq 6$is the correct inequality representing the shaded solution region.
