Answer 1

Step-by-step explanation:

Plot the following points and check whether they are collinear or not

(i) (X 3), (-X -1), (-2, – 3)

(ii) (1,1), (2, – 3), (-X – 2)

(iii) (0,0),(2,2),(5,5)

Thinking Process

(i) Firstly, plot all three points on a graph paper and join them.

(ii) If it lives a straight line, then points are collinear otherwise non-collinear
