The task is this: you have to place 51 rows of 50 points. So you must be able to draw 51 times a straight line so that there are 50 points on each line. What is the minimum number of points I need to do this. Thank you very much in advance.

There must be some way these lines can intersect, otherwise the answer would be equally trivial. I can easily think of a way of doing it with 100 points, but I don't know if it's 'allowed' or not.

This question is one of the first problems of a new site called http://www.raadselman.be, this is a competition where everyone has to send in his answers within a week. Afterwards they make a ranking so after a couple of weeks/months they see who is the best riddlesolver.
