In a warehouse logistics map, a conveyor belt is positioned along the line $y = -5$. A technician must install a safety sensor path that is perpendicular to the conveyor belt and passes through the coordinate point $(-4, -5)$. Match each element of this installation to its correct geometric or algebraic description.

In a data center floor plan, a row of server racks is aligned along the horizontal line $y = -5$. A technician states that any cooling conduit installed perpendicular to this row that passes through the point $(-4, -5)$ must follow the vertical line equation $x = -4$. Is this technician's statement true or false?

In a digital blueprint for a new office layout, a main water pipe runs along the horizontal line $y = -5$. An architect needs to draw a perpendicular pipe that connects to a sink located at the coordinates $(-4, -5)$. The equation for this vertical perpendicular pipe is ____.
