Answer:

  • B) y = 0.6x

Explanation:

Proportional relationship equation:

  • y = kx, where k- coefficient of proportionality.

Use given values in table to find the value of k:

  • 9 = 15k ⇒ k = 9/15 = 0.6
  • 7.2 = 12k ⇒ k = 7.2/12 = 0.6
  • 1.5 = 2.5k ⇒ k = 1.5/2.5 = 0.6

So the equation is:

  • y = 0.6x
