Solution
if the points are collinear then only 1 line can pass through 3 points
as colinear mean the points which are on same line
b) If the lines are non collinear
if line should be pass through all three points then answer is none because non collinear means the points which not lie in a line
if it must contain only two points then number of line will be three ..because we can draw a triangle
