Finding the Equation of a Line Perpendicular to $y = 1$ Through $(-5, 1)$

Finding the Equation of a Line Perpendicular to $y = -5$ Through $(-4, -5)$

A construction crew is using a coordinate grid to lay out a new building foundation. They have established a baseline for one wall along the horizontal line $y = -3$. A second wall must be built perfectly perpendicular to this baseline so that it passes through a specific survey marker located at the point $(-3, 5)$. What is the equation of the line that represents the second wall?

In a computerized machining plan, a reference groove is milled along the horizontal line $y = -3$. A new groove must be milled perpendicular to this reference line, passing exactly through a target hole at the coordinates $(-3, 5)$. The equation that programs this new perpendicular cut is $y = 5$.

A maritime navigator is plotting a course on a nautical chart. The primary shipping lane is defined by the line $y = -3$. A service vessel needs to travel along a path perpendicular to the shipping lane that passes through a buoy located at $(-3, 5)$. Match each geometric component of the navigator's mapping task to its correct algebraic description.

A city surveyor is mapping a new underground fiber-optic cable. The main utility line is represented by the horizontal line $y = -3$. The new cable must be laid perpendicular to the main line, passing through a connection hub at the coordinates $(-3, 5)$. Order the following steps in the correct logical sequence to determine the equation for the new cable's path.

In an architectural CAD (Computer-Aided Design) software, a horizontal reference beam is plotted along the line $y = -3$. A draftsperson must draw a perpendicular support column that passes exactly through a load-bearing joint located at the coordinates $(-3, 5)$. Recalling that any line perpendicular to a horizontal line must be a vertical line, the draftsperson sets the equation for the perpendicular support column's path as $x =$ ____.
