Step 1

(a) Recall the fact that the two vectors originating from the same point are parallel if they are multiples of each other.

Step 2

(b) Recall the fact that the two vectors originating from the same point are parallel if they are multiples of each other.

Step 3

(c) Recall the fact that the two vectors originating from the sam...
