A =(1, 0, -1) don't remember B/C

I know that there were 4 parts:
(a) line through AB - don't remember the vectors for r=a+(t)b
(b) finding the plane, r.n=p and yeah, p=3 and i think n=(4,-5,7) or something
(c) intersection of plane/line? I don't remember
(d) yes, 1/sqrt(10) [d=a.n/|n|]

I will revise the FP3 boundaries when I attempt the paper
15. Think I dropped around 13 marks, was so gutted to see two co-ordinate geometry questions though
