Learning Objectives for Graphing Linear Inequalities in Two Variables
The instructional goals for this section identify four key skills. First, learners must verify solutions to an inequality in two variables. Second, they need to recognize the relationship between the solutions of an inequality and its visual representation. Third, they will actively graph linear inequalities in two variables. Lastly, they will logically solve applied word problems involving linear inequalities built over two variables.

In a corporate budgeting scenario, a manager needs to ensure that the combined cost of labor x and materials y does not exceed the total allocated funds C. Which of the following represents the standard form of a linear inequality in two variables used to model this constraint?
In business modeling, we often use linear inequalities to represent constraints like budget limits or production goals. Match the following terms related to the definition of a linear inequality in two variables with their correct descriptions.
In a corporate resource allocation model, a linear inequality in two variables (such as Ax + By < C) is used to define a range of possibilities. Unlike a one-variable inequality where the solution is a single number, the solution to this type of inequality is a set of ____.
In a corporate budget model, a linear inequality in two variables—such as —defines solutions as individual numbers that are graphed on a one-dimensional number line.

A project coordinator is using a coordinate graph to monitor a labor constraint where the combined hours of two teams, and , must be less than or equal to 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 and its height 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.
