Question

please answer fast please​

Answer 1

Answer:

use the formula AB=BC=CA

if the result is same than it is collinear

Answer 2

Step-by-step explanation:

The best way to find that lines are collinear or not is that assume that these coordinates are forming triangle then apply the formula of the area of the triangle in the case of coordinate geometry and if the ans came out to be 0 then it means that points are collinear because collinear points have area equal to 0 and if the ans is coming in numerous form then these points are not collinear.

NOTE: If ur ans comes negative then don't get confused it is just because taking different orders of coordinates suppose if ans comes -4 then the area would be absolute value of -4 that is always positive that is 4.
