A problem in direction field

  1. Oct 28, 2013 #1
    1. The problem statement, all variables and given/known data

    I posted a similar type of question earlier. But somehow, i figured out how to do it. For this question however, I have no clues how to do it. The word document having the image is attached

    Which of the following di erential equations corresponds to the direction field
    shown below?

    y'=x+y
    y'=(x-1)(y-1)
    y'=(x+1)(y-1)
    y'=(x-1)(y-1)
    y'=y-1



    2. Relevant equations

    This doesn't need a known equation rather than understading the direction field

    3. The attempt at a solution

    For the first glance I know that y = 1 is an equillibrium solution. However, I have no idea how to deal with the horizontal lines found at x=1??? Any Help??
