    by y = -x(2) - 5 I assume you mean -x^2 - 5?

    and y = x - 5 isn't a parabola, it's a straight line.

    also shouldn't you be working these out yourself?

    Asking the forums is pretty much weird.
    Review your lessons or have someone teach you.

    Re: Math

    i think can use simultaneous equations... sub y = x - 5,

    so x - 5 = -x^2 - 5

    then shift it over

    x^2 - x = 0

    then solve it

    x = 0 or x = -1

    i think i am right :)
