There are 5 lines. These lines intersect in 5 points.
5 lines can not be parallel. In that case, there will be no point of intersection.
If 4 lines are parallel, then one balance line can intersect them at 4 points only.
If 3 lines are parallel, then balance 2 lines can make 5 points of intersection.

Not possible for intesecting at 5 points if more than 3 lines are parallel.

If there are more than 3 parallel lines out of 5 lines, they can not intersect at 5 points.

If all lines are parallel.. No intersection.
If only one line is intersecting 4 lines, it can intersect at max 4 pts.

so 3 lines can be parallel and two intersecting lines.

----------

---------- three lines will be horizontal... one will be vertical...and another line will cut at the intersection of 1st horizntal and vertical line and cross 2nd and 3rd horizontal line.... so there are 5 intersection points....
