Question

What is Collinear points how many lines can you draw passing through five Collinear points

Answer 1

Answer:

Three or more points in a plane are said to be collinear if they all lie on the same line.

Five line draw on five collinear point

Answer 2

Since they are collinear we get only one line out of these 5 points instead of 10. So, the total number of straight lines that can be drawn through 13 points on a plane with 5 of the points being collinear is 78 - 10 + 1 = 69.
