y=-4x+4

Explanation:

  1. Use point slope equation: (y_2-y_1)/(x_2-x_1)
    (-8-4)/(3-0)=-12/3=-4
  2. f(0)=4 They give you the y-intercept in this problem.
  3. Apply to slope equation: y=mx+b
  4. Linear function: y=-4x+4
    Note: To check your work, graph the linear equation and see if the points match at (0,4) and (3,-8).
