There are n points in a plane of which p points are collinear. How many lines can be formed from these points
Text Solution
Verified by ExpertsThe correct answer is:
C
Given, total number of points = n and number of collinear points = p . We know that one line has two end points. Therefore total number of lines =
. Since p points are collinear, therefore total number of lines drawn from collinear points =
. We also know that, corresponding to the line of collinearity, one will also be added.
Therefore number of lines =
