Question

(1, 2), (-5, 6) and (k, -2) area of triangle is =0 find the value of k​

Answer 1

Step-by-step explanation:

if area of triangle is 0, then points are in collinear

if the points are collinear, then slopes formed by any two points are equal

slope of (1,2), (-5,6)= 6-2/-5-1=4/-6=-2/3

slope of (1,2), (k,-2)= -2-2/k-1=-4/k-1
