Question

Plot the following points and check whether they are collinear or not :
$\left(i\right)(1,3),(-1,-1),(-2,-3)$
$\left(ii\right)(1,1),(2,-3),(-1,-2)$
$\left(iii\right)(0,0),(2,2),(5,5)$

Answer 1

(i) From the graph, we find that all the three points lie on the same straight line. Hence, the given points are collinear.

(ii) From the graph, we find that all the three points do not lie on the same straight line. Hence, the given points are not collinear.

(iii) From the graph, we find that all the three points lie on the same straight line. Hence, the given points are collinear.
