(3, -4) is on the line because the equation is point-slope equation where the point (x1, y1) is;
y - y1 = m(x- x1)

2x+2y=8 in function form step by step please?

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.
