Warehouse Pathway Layout Slopes

A warehouse operations assistant is using grid-mapping software to plan new pathways. To ensure the layout is safe, some pathways must run parallel to existing ones, while others must intersect at right angles (perpendicularly).

To complete this layout task successfully, state the two mathematical rules regarding slopes that the assistant must recall:

  1. What is the relationship between the slopes of two parallel lines?
  2. What is the relationship between the slopes of two perpendicular lines (assuming neither is vertical)?
