Answer:
Step-by-step explanation:
Part A: the x-components of the two vectors are the same, except that one points in the opposite direction as does the other. Same with the y-components. Thus, the two vectors are parallel.
Part B: The x-components of the two vectors are 2 and -3, meaning that -3 is the constant -3/2 times 2. The y-comps of the vectors are 3 and -2, and -2 is NOT -3/2 times 3. Therefore, the two vectors are NOT parallel.
