    Poop

    Never the less ... I am sure that the OP can sketch a diagram
    That's the really funny thing; there's a diagram given in the question.

    I've already knew what the height and base were though, the problem is an error I'm making in the distance formula which I can't figure out, I already knew the base had a distance of 3, it's when I substitute the OB coordinates in to the distance formula, I keep making some arithmetic error, I can see the distance is 6 too but when I try to prove that it is actually 6, I don't get 6.

    OB IS NOT 6

    Why would it be

    It is the hypotenuse of a triangle with sides 1 and 6

    As you have said OB = root (37)

    yes that clears up my confusion, I was finding the wrong height and didn't find the perpendicular height, thanks

    You're welcome.

    I'm sure you were just having a blank moment or two or three. I'm sure another time you'd get this straight away.

    Working too hard on new year's eve?

    Yes, I've been doing past papers 24/7 for maths for the last 2 days so I end up getting the really long ones right and mess up the easy ones by over-thinking every little thing!

    Yes, I can tell where the base and height are now and have one distance of 3. I can't seem to get 6 for the distance of OB though, I'm making some error in the distance formula even though I've checked my working loads

    EDIT; Sorry my diagram was wrong.
