B represents a proportional relationship

Answer:

B) y = 5x

Proportional relationships are relationships that:

  • follow the form y = kx (k = constant of proportionality)
  • have a y-intercept of 0 (they go through the origin)
  • have a constant of proportionality.

Thus, the equation that follows y = kx is B) y = 5x.
