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

    x = 6-8t
    y = -1-2t
    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=6-2t

    y=-1+t(-3)
    y=-1-3t

    z=5+6t

    is that correct? ...
