There are 7 points on a plane. Three of them are collinear. Find the maxmimum amount of distinct line that can be made from these 7 points.

From each of the non-colinear points to each poin on the line would be 4 x 3 = 12 lines

from each of the 4 to the other three would (4 x 3)/2 = 6 lines

PLUS the colinear line

19 lines (I believe)
