    Mast C1 Past paper question help



    I'm interested in part D - I've looked at the mark scheme and you need to square AC somehow but I don't really understand it, if someone can have a go at the question and let me know how they got the 'show that' answer it would be great, thanks.

    you use pythagoras

    same as you did in (c)


    C is (p,y)

    where y is found by using the equation in part (a)

    (Original post by freedomyak)
    ...
    The co-ordinates of C are \displaystyle \left(p, \ - \frac12p + 6 \right)

    The co-ordinates of A are (2, \ 5)

    AC = 5

    Use, AC^2 = (y_2-y_1)^2 + (x_2-x_1)^2
