good luck i hope you do well on the quiz btw the answer is:
Collinear because any points that is "on" the same line is considered collinear.
It can be Coplanar when any 3 points lie in the same plane, but this problem does not say that. It only asks if point U can be anywhere on the line including R and N.
Hope this helps! :) thanks to:
