    minimize the square

    Why do we want to minimize the square difference from a point to the line instead of the actual difference when using the least squares method?
    checkbox select:
    1. It's more accurate to minimize the larger value
    2. We could minimize the actual difference as well
    3. We want to ensure the values is positive because it is a distance
    4. We want to ensure that far away points are weighted more heavily than nearby points.

    I think select 1, 2, 4 are right.
    But i can not sure.
    Anyone can give me some advise?
