Answer:

  • A. y = 5x

Step-by-step explanation:

Direct proportion equation:

  • y = kx, where k is the coefficient of proportionality

We have:

  • x = 3 and y = 15

Using the equation to find the value of k:

  • 15 = 3k
  • k = 15/3
  • k = 5

The equation of the line:

  • y = 5x

Correct choice is A
