Hi, I have a problem which I can't solve, so I hope someone can help me. 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.

Fifty, if there is no restriction on the intersections of the lines.

50 points? Of course not, then I only have 1 row of 50 points. I need 51 rows of 50 points.

But you didn't specify that the lines had to be different. 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.
