lets say you have to write 5x+6y=-12 in function form.
when you are writing an equation in function form, you usually solve for f(x) or g(x), but in this case, y is the same as f(x) or g(x). so to write 5x+6y=-12 in function form, you do this:
5x+6y=-12
6y= -5x -12 subtract 5x from both sides
y= -5/6x -2 divide both sides by 6
y=3x+12
1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.

f (x) = 2/3 x + 2
If you mean: 2x+3y = 12 then y = -2/3x+4 whereas -2/3 is the slope and 4 is the y intercept
y=3x+12
You need it in the form f(x)= ... (whatever your equation happens to be). i.e get the equation in the form y=... Then swap the 'y' for 'f(x)'. Simple.
1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.
y = 16X - 80

It is not an equation because it doesn't have an equal sign in it so to write it in slope-intercept form is impossible
f (x) = 2/3 x + 2
If you mean: 2x+3y = 12 then y = -2/3x+4 whereas -2/3 is the slope and 4 is the y intercept

Makes no sense as written.
The equation of the line is written in the standard form, y = mx+c
== == y = -x + 5
