4y = -x - 8

y = (-1/4)x - 2, that's y as a function of x

x = -4y - 8, that's x as a function of y

First, solve for y:

x + 4y + 8 = 0

4y = -x - 8

y = (-1/4)x - 2

Then change the y to f(x):

f(x) = (-1/4)x - 2

That's your equation in function form.

Put the equation in slope, y-intercept form y = mx +b, ie., y = -(1/4)x - 2.
