Part 1
Answers: point Q, point R, point S
-----------------
Step-by-step explanation:
All three points mentioned are on the same straight line; hence they are collinear.
=======================================================
Part 2
Answer: Point T or point W
Pick one of those answers only
-----------------
Step-by-step explanation:
Notice how point W is not on the line shared by points Q, R, and S. The same can be said about point T with that line.
So we would say that the set {T, Q,R,S} is not a collinear set of points. We could also say {W, Q,R,S} is also not collinear.
