Question 228264
You want the problem to look like this to find slope any y intercept:

y=mx+b

(m=slope)(b=y-int)

{{{2x+2y-4=4x+2}}}

Now, you would move the 2x from the left side to the right side of the equation by subtracting.

{{{2y-4=4x-2x+2}}}
combine like terms on the right side of the equation by adding the x's together.

{{{2y-4=2x+2}}}

Next, you would do the same thing with the -4.

{{{2y=2x+2+4}}}

Then, combine like terms again

{{{2y=2x+6}}}

Now, get y by itself completely by dividing 2 on both sides of the equation

{{{2y/2=2x/2-6/2}}}

After you simplify 

{{{y=1x-3}}}

Now, you can determine the slope and y intercept

slope(m)= 1

y intercept(b)=-3
