I think you are saying that if you are given a pair of ordered pairs and a single coordinate (either 
or 
) of a point on the same line that passes through the two given points, find the other coordinate.
Use the two-point form of an equation of a line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Once you have substituted the known values, solve the equation for the remaining variable.
