Thanks again that totally clears it up for me.
will do nicely.
so you have
x = 2 + 3t
y = 4 - 4t
z = -1 + 8t
Don't ignore the z component ... rather make it equal to zero
0 = -1 +8t
solve for t
That fixes the value of t and so you can put back into the x and y equations to get the point as three numbers.

Hi all I recently started linear algebra and my prescribed book seems to require some 3-dimensional geometry knowledge which i've never touched... Any idea how to go about this?
