A small business uses a specialized software service that charges a flat monthly maintenance fee of ${}4$ dollars, regardless of the number of users ($x$). This relationship is represented by the equation $y = 4$. When graphing this cost by plotting points, which set of ordered pairs correctly reflects that the $y$-coordinate must remain constant at ${}4$?

A quality control inspector is charting a machine's output pressure, which must remain steady at 4 units. This constant pressure is modeled by the equation $y = 4$. When creating a table of values to graph this equation by plotting points, the inspector must only generate ordered pairs where the $y$-coordinate is 4, regardless of the $x$-coordinate.

An office manager is graphing a fixed monthly service fee of 4 dollars per employee, which is modeled by the equation $y = 4$. Arrange the following steps in the correct order to graph this relationship using the point-plotting method.

A company's software subscription charges a flat monthly 'Cloud Access Fee' of 4 dollars, regardless of how many gigabytes of data ($x$) the user uploads. This relationship is modeled by the equation $y = 4$. To graph this fee structure using the point-plotting method, an administrator must identify the correct coordinates for their table of values. Match each component of the graphing process with its correct description in this context.

Graphing Constant Coolant Flow Rates

An inventory specialist is creating a chart to track a warehouse's fixed daily safety stock requirement of 4 pallets of a specific item, regardless of the day of the week ($x$). This constant requirement is modeled by the equation $y = 4$. Because the $y$-value does not depend on $x$, plotting ordered pairs like (1, 4), (3, 4), and (5, 4) and connecting them on a coordinate plane will always produce a ____ line.
