A GIS mapping technician is entering the coordinates for two new utility lines into a city's database. Line A follows the equation $y = -3x + 2$ and Line B follows $x - 3y = 4$. To install a right-angle connection box, the technician must recall the procedure to verify these lines are perpendicular. Arrange the mathematical steps the technician recalls in the correct chronological order.

An interior designer is planning two decorative trim lines on a floor layout, represented by the equations $y = -3x + 2$ and $x - 3y = 4$. To verify that these lines meet at a right angle, match each component of the perpendicularity check with its correct numerical value.

A warehouse maintenance technician is inspecting two floor-mounted conveyor tracks for a new sorting system. Track A follows the equation $y = -3x + 2$ and Track B follows the equation $x - 3y = 4$. True or False: These two tracks are perpendicular.

Drafting Perpendicular Circuit Paths

A junior CAD designer is verifying if two crossing pathways on a park blueprint are perpendicular. The first pathway is represented by the equation $y = -3x + 2$, and the second pathway is represented by the equation $x - 3y = 4$. To confirm that these two pathways meet at a perfect right angle, the designer calculates the product of their slopes. The product of the slopes of these two perpendicular lines is ____.
