A financial analyst is mapping out a chart where a specific cost trajectory is modeled by the linear equation $y = -x$. When the analyst attempts to graph this equation using the intercept method, why is it necessary to calculate additional points beyond the x-intercept and y-intercept?

A corporate training module on budget balancing uses the linear equation $y = -x$ to represent perfectly offsetting costs. Arrange the following steps in the correct order to graph this relationship using the intercept method as described in the course materials.

When graphing the linear equation $y = -x$ using the intercept method—a common model for representing perfectly offsetting balances in business—the x-intercept and y-intercept provide two distinct locations on the rectangular coordinate system to define the line.

Graphing Carbon Neutrality Models

A retail logistics analyst is graphing a model of 'Offsetting Inventory' where $y = -x$ represents the relationship between stock levels in two regional warehouses. Match each component of the graphing process with its corresponding value or location based on the standard procedure.
