A project coordinator is using a coordinate-based planning tool to design a facility layout. To ensure that two utility lines are perpendicular to each other on the grid, which rule about their slopes must be followed?

An urban planner is plotting a new crosswalk on a digital city grid software that must intersect the main road at a perfectly perpendicular angle. To calculate the exact equation of the crosswalk line, the planner must set its slope to be the negative ____ of the main road's slope.

A civil engineering technician is using CAD (Computer-Aided Design) software to plot new infrastructure on a city grid. Match the desired alignment of the pipelines with the correct mathematical rule for their slopes.

A project planner is using a coordinate map to design a new access road that must run parallel to an existing highway. Arrange the following steps in the correct order to determine the linear equation for the new road.
