Question

Which of the following points will lie on the same line.

  1. (-2,2) ,(3,2), (-5,2)
  2. (-1,3) ,(2,4), (3,5)
  3. (1,2) ,(2,3), (3,4)
  4. (-1,-1) ,(-2,1), (0,2)
     

The correct answer is: (-2,2) ,(3,2), (-5,2)


    The points which lie on the same line must be collinear.
    In this question we have to check the option for collinearity.
    Step1: Checking for collinearity for the set of points left parenthesis negative 1 comma negative 1 right parenthesis space comma left parenthesis negative 2 comma 1 right parenthesis comma space left parenthesis 0 comma 2 right parenthesis
    For three points A,B,C to be collinear the below relation between the distances of the point must hold.
    D i s tan c e space A B space plus space D i s tan c e space B C space equals space D i s tan c e space A C
