Summer Assignment Test

I got half a point off of problem number 3. Here is the problem redone:
       2/2x-5+3
       2/2x-2
       1/x-1
I also got number 6 wrong. Here is the problem redone:
       A. 13x-20y+40=0
            13x+40=20y
            13/20x+2=y wrong slope and right y-intercept
***answer I originally put because I only looked at the y-intercept***
      B.  3x+2y-1=0
           3x-1=-2y
            3/2x+1/2=y wrong slope and wrong y-intercept
      C.  4x-3y+6=0
            4x+6=3y
            4/3x+3=y right slope and right y-intercept
***correct answer***
      D.  6x-3y=0
            6x=3y
            2x=y wrong slope and wrong y-intercept

These are the only two problems that I got points off on. I found the test to be fairly easy because most of it was review from Algebra I and II.
