Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:

с 1 and 3

What is a proportional relationship?

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the functions and constants are given as follows:

  • 1. 4y = 3x -> k = 3/4.
  • 2. 8y = 5x -> k = 5/8.
  • 3. 8y = 6x -> k = 6/8 = 3/4.
  • 4. 5y = 8x -> k = 8.5.

Equations 1 and 3 have the same constants, hence option c is correct.
