1. a) Write the vector and parametric equations of the line through the points A(6, 1, 5) and B(2, 3, 6).
b) Find another point on the line in (a).

r = 6ij+5k + t(8i2j+k)
x = 68t
y = 12t
z = 5+t

Can you please do b) Steve? Thank you.

Steve, for a) I got this instead:
vector equation:
[x, y, z] = [6, 1, 5] + t[8, 2, 1]
parametric equation:
x=6+t(2)
x=62t
y=1+t(3)
y=13t
z=5+6t
is that correct? ...
