A logistics coordinator is mapping the placement of two vertical support columns on a warehouse floor plan grid. The first column is located at the point $(5, 1)$ and the second column is located at $(5, -4)$. Which equation correctly represents the vertical line that passes through both column locations?

A CNC programmer is verifying the toolpath for a vertical cut on a metal sheet. The cut starts at $(5, 1)$ and ends at $(5, -4)$ on the machine's coordinate grid. When calculating the slope of this toolpath, the denominator evaluates to zero. This means the mathematical slope of the line is ____, resulting in the vertical line equation $x = 5$.

A CAD technician is documenting a vertical boundary line on a coordinate grid that passes through the points $(5, 1)$ and $(5, -4)$. The mathematical equation that defines this vertical line is $x = 5$.

A structural surveyor is marking a vertical boundary on a coordinate grid that passes through the points (5, 1) and (5, -4). Arrange the following steps in the correct order to recall the mathematical procedure for determining the equation of this vertical boundary.
