Three drone cameras A, B and C are recording a hockey match. Their positions with respect to a control tower O are given by the following coordinates:
$A(1, 4, 6)$, $B(3, 4, 5)$ and $C(5, 4, 4)$.
Using vector method, show that the drone cameras A, B and C are moving in a straight path while recording the match.
Given: Positions of drone cameras: $A(1, 4, 6)$, $B(3, 4, 5)$, $C(5, 4, 4)$.
To show: Drone cameras A, B and C are moving in a straight path (collinear).
