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 = 6i-j+5k + t(-8i-2j+k)

x = 6-8t

y = -1-2t

z = 5+t

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=6-2t

y=-1+t(-3)

y=-1-3t

z=5+6t

is that correct? ...
