First, parallel vectors are scalar multiples of each other so although it looks promising how 4*-5=-20 and -1*-5=5 the third value does not hold up, so it is not parallel. Second, orthogonal vectors are perpendicular, so they will have the dot product of 0 but when you preform the dot product operation here, you get -80 -5 +85=0 so it is orthogonal... Show More
I believe it’s neither but I’m not totally sure… Sorry.... Show More
