Which of these equations show a proportional relationship

FlexZone
PowerFitness
both
Neither

1 answer

To determine whether any of the given equations show a proportional relationship, we need to analyze them. A proportional relationship typically has the following characteristics:

  1. Directly proportional - If one quantity increases, the other quantity increases as well, at a constant rate.
  2. Linear relationship through the origin - The equation can generally be expressed in the form \( y = kx \), where \( k \) is a constant. In this case, if \( x = 0 \), then \( y \) must also equal 0.

If you could provide the specific equations for "FlexZone" and "PowerFitness," I would be able to analyze them and determine which, if any, demonstrate a proportional relationship.
