Given n points in the Euclidean plane. We draw a line through every pair of points. The Sylvester-Gallai theorem asserts that if all the points are not colinear then there must exist a line that passes through exactly 2 of the given n points (called an Ordinary line) We study proofs that show the existence of many Ordinary lines.
