Let L be the line with parametric equations

x = −7+3t
y = −6+2t
z = −3+3t

Find the vector equation for a line that passes through the point P=(8, −8, −9) and intersects L at a point that is distance 4 from the point Q=(−7, −6, −3). Note that there are two possible correct answers. Use the square root symbol '√' where needed to give an exact value for your answer.
The correct answer is:
