Question

In each of the following find the value of ‘K’, for which the points are collinear.
(8, 1), (k, -4), (2,-5)​

Answer 1

Answer:

if the points are collinear, the slop will be same for all pairs of points.

Slope of line joining (8,1) and (2,-5) =  (1- -5)/(8-2) = 6/6 =1

Therefore, slop of line joining (8,1) and (k,-4) should be 1

(1 - -4)/(8-k)=1

8-k =5

k=3
