    Red face Emergency Panicking (NO TIME) Please Help! Year 10 Maths.

    Hello Girls and Guys I am really in bit of a pickle here as to how to do this mini maths problem which is due Monday. My teacher is hopeless as she just dumps the work without explanation on us. My girlfriends can hardly help as they have a high amateurishness threshold towards mathematics, as do I. Help would be appreciated. My contact email is lesbianista@hotmail.com. Oh and by the way we got this on Friday to do over the weekend.

    Problem
    An aeroplane has
    crashed in the desert at
    a point that could be
    labelled (−15, 12) on a
    particular grid system.
    A search party sets out
    by 4WD from the point
    (18, 3) and travels in a
    straight line passing
    through the point (3, 9).
    A light plane sets out
    from point (3, −15) and
    travels in a straight line
    passing over the point
    (−3, −6).

    1. Will either of the search parties pass the point where the aeroplane lies if they continue
    on these paths? Explain how you obtained your answer.
    2. If either (or both) of the original routes does not pass the point where the aeroplane lies,
    give a different point (but with the same x-coordinate) that the searchers should pass
    through (or over) to be on course to locate the aeroplane.

    How my teacher wants it set out

    1) Draw a labelled Diagram of information given in 2-D with a labelled set of axis and points clearly labelled.
    2) Use above diagram to write equation of line created by both search parties (with working)
    3) Show algebraically whether each party will pass where the plane crashed.
    4)If either or of both planes do not line on the correct path;
    (a)Find a new point (but with the same x-coordinate) that the searches should pass over to be on course to find the aeroplane.
    (b) Prove algebraically that this new route will find the aeroplane.

    Thanks

    First this is a homework problem. We do not do your homework. Show us how far you have got on it.

    Second this is the forum to introduce yourself, not a forum to submit questions.
