Answer:

  (x, y) = (t -3, 4t)

Step-by-step explanation:

Here's one way to do it.

Write the equation in slope-intercept form, then factor.

  y = 4x +12

  y = 4(x +3)

Now, define ...

  t = x+3

  x = t -3 . . . . . solve for x

Substitute t in the equation for y:

  y = 4t

Now, our parametric equation is ...

  (x, y) = (t -3, 4t)
