• A maze.

What is the significance of the origin in the vector equation for line OS?

• It is irrelevant to the equation.

• It requires an additional position vector.

• It complicates the equation.

• It simplifies the equation as no further position vector is needed.

What parameter is typically used in vector equations to indicate direction?

• Alpha

• Beta

• Lambda

• Gamma

How is the direction vector for line PR derived?

• By subtracting vector P from vector R.

• By using the midpoint of the line.

• By adding vector P to vector R.
