I can't think of a way to "show that y=...". Do I compare to x values?
Thx
I don't even know what that means!thomas49th said:(x,y) - (x,0) = (x,y) -(0,2)
is that right?
Nooo!thomas49th said:LHS
x - x = 0
y - 0 = y
RHS
x - 0 = x
y - 2 = y - 2
SO
y = x + y - 2
x = 2
that right?
I thought most people would have seen that formula at least a couple of years before they turn 16!thomas49th said:ive never ever seen that formula in my life, and I think it is beyond GCSE level (that exams you do in UK when your 15 or 16). Is that formula the simplest way?

It is. You're right.cristo said:Is it not just Pythagoras' Theorem in a different guise?

Well, cristo would follow Halls' hint, using Hootenanny's formula for the distance, and then set them equal.how would cristo go about solving it then?
thomas49th said:What did I do wrong when I add/subtracted the co-ordinates? I know you can only add/subtract the x from x and y from y. I had a look here http://www.bbc.co.uk/schools/gcsebitesize/maths/shapeih/transformationshrev2.shtml
Can someone point me in the right direction.
Is (x,y) - (x,0) = (x,y) -(0,2) right?
The webpage above is for vector displacement not distance between points.

thomas49th, if you are serious about this, then this suggests that you are either misplaced in your course, or you are studying on your own and beyond your level of achievement. What course are you enrolled in? IF you are enrolled in "Algebra 2" or Intermediate Algebra, then you have been taught the distance formula. In case you are just now in the course being introduced to the distance formula, then study your book very carefully. Again, as reminder, you probably will find an example in your book much like the question which you have here been asking.thomas49th said:So how do I find the distance between points?
