Answer:

  4/3

Step-by-step explanation:

The constant of proportionality is the coefficient of x when the equation is in the form ...

  y = kx

Dividing the given equation by 6 will put it in that form.

  6y = 8x

  y = (8/6)x

  y = 4/3x . . . . . reduce the fraction

The constant of proportionality is 4/3.
