Finding the Equation of a Line Perpendicular to $x = 2$ Through $(2, -1)$

In a computer-aided design (CAD) program used for warehouse floor planning, a main shelving unit is aligned along the vertical reference line $x = 4$. You need to draw an aisle that is exactly perpendicular to this shelving unit and passes through the reference coordinate $(4, -5)$. Recalling the rules for perpendicular vertical and horizontal lines, what is the equation of the line representing the new aisle?

In a technical drafting application, a vertical reference boundary is defined by the equation $x = 4$. To place a perpendicular support line through the point $(4, -5)$, you must use a horizontal line equation. Given that horizontal lines follow the form $y = b$, the specific equation for this line is ____.

A drafting technician is programming a robotic cutter to move along a path perpendicular to a vertical guide rail defined by the equation $x = 4$. The path must pass through the point $(4, -5)$. Match each aspect of this task to its correct mathematical property or value.

In a municipal mapping application, a utility line is planned to run perpendicular to a vertical property boundary defined by the equation $x = 4$. The utility line must pass through a connection point located at $(4, -5)$. Arrange the following steps in the correct order to recall the properties and determine the equation for this utility line.
