Let A = (1, 5, 3) and B = (6, 8, 4). Suppose P = (41, y, z) is collinear with A and B. Find y and z.

The vectors B-A and P-B must be parallel

B-A = (5,3,1)
P-B = (35, y-8, z-4)

Thus y-8 = 7*3
y = 29

z-4 = 7*1
z = 11

Draw it out... look in your book and you can figure it out once you have a picture to go with it.
