Question

Show that the points (5,4,2), (6,2,-1),
(8,-2,-7) are collinear.​

Answer 1

Explanation:

use slope form of use centroid formula OK friend

Answer 2

Given (5,4,2),(6,2,−1),(8,−2,−7)

(x1,y1,z1)=(5,4,2)

(x2,y2.z2)=(6,2,−1)

(x3,y3,z3)=(8,−2,−7)

(x1−x2)/(x2−x3) = (y1−y2)/(y2−y3) = (z1−z2)/(z2−z3)
