Your query could refer to two things :-

If you are referring to the distance between two points given their 3D
coordinates then yes you can do it like so :-

y (distance) = ((x1 - x2)^2 + (y1 - y2)^2 + (z1 - z2)^2)^0.5

If this is not what you are wanting to do and it is something close to
what Derek suggested then again you should be able to get the solution
for 'y' given the relationship between x and z - which you have not
explained. You may want to do that if you want better explanation on
this count.
