Answer :
You could get two different functions out of this:
2x + 2y = 8
1). 'y' as a function of 'x'
Subtract 2x from each side: 2y = -2x + 8
Divide each side by 2 : y = -x + 4
2). 'x' as a function of 'y' :
Subtract 2y from each side: 2x = -2y + 8
Divide each side by 2 : x = -y + 4
Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical. In general, they're
not the same function.

Starting with 2x + 2y = 8
The first step is to subtract the monomial including x from both sides.
2x + 2y = 8
-2x -2x
The result is 2y = -2x + 8
The next step is to isolate y, which we must divide both 2y and -2x + 8 by 2 to achieve.
2y = -2x + 8
/2 /2
The result is y = -x + 4, which is now in function(slope-intercept) form.
