[Question]
if I have a list of coordinate... let say...
(2, 17)
(3, 25)
(4, 19)
(5, -1)
can u find an equation which can suit all the coordinate above...???
(I suppose... it also will work for more than this number coordinate,
it can be five or more)....
Hopefully there is some one that can help me...!!!

May be I change another way

let say:
x-2y=17                       (2, 17)
x-3y=25                       (3, 25)
x-4y=19                       (4, 19)
x-5y=-1                       (5, -1)

Is what my Idea loh... previously I just give a list of
coordinate... and require to produce or figure out an
equation which able to solve the problem... where...
when I....

-> insert 2 in to that equation.... it able to output 17 as
a result....
-> insert 3 in to that equation.... it able to output 25 as
a result....
-> insert 4 in to that equation.... it able to output 19 as
a result....
-> insert 5 in to that equation.... it able to output -1 as
a result....

is that POSSIBLE...??? [ Hopefully is possible].....
plz..... is urgent.... S.O.S~......

An Idea.... just an Idea.....
Now... I assume there is a equation for each coordinate....
where it is in the form of....

   -> x-Ay=B           (A, B)
   -> where, A={0, 1, 2, 3..... n}, and B is the result.....

:. If there is a possible to solve x, y from that list of
equation.... there might be possible.... or any one got
better idea...

plz.... help me..... S.O.S.... is urgent to solve some
problem...... 0_o???

"Plz reply me as soon as possible....." S.O.S~......
