A project coordinator is using a coordinate graph to monitor a labor constraint where the combined hours of two teams, $x$ and $y$, must be less than or equal to 160 ($x + y \le 160$). Which visual feature of the graph specifically indicates that the case where the total is exactly 160 hours is included in the solution set?

A city planner is using a Geographic Information System (GIS) to map out zoning restrictions for a new urban development. They use linear inequalities to define allowable zones where a building's distance from the street $d$ and its height $h$ must meet specific safety codes. Match each mathematical component used in these zoning inequalities with its corresponding visual representation on the planner's digital map.

A logistics coordinator is training a new team member to visualize delivery constraints on a coordinate map using linear inequalities. Arrange the following steps in the correct standard sequence for graphing a linear inequality in two variables.

A facility manager is using a coordinate graph to monitor a safety threshold where the noise level $x$ and vibration level $y$ must satisfy the inequality $x + y \le 85$. In this visualization, a solid boundary line is used to indicate that the scenario where the total is exactly 85 is included in the solution set.
