Ax+by=c is standard form, so first, you need to distribute the 4 to inside the parenthesis, so now the equation becomes y-2 = 4x-4, next you need to get x and y on the same side and get the c variable onto the right side of the equation, subtract 4x from both sides, now we have y-2-4x =-4, now add 2 to both sides to get c by itself. Now the equation should look like this, -4x+y=-2. This is the equation now in standard form. Hope this helps.
