A:
Well you can't.
There are two things missing, v and t. The quantities x and y are positions along two mutually orthogonal directions. The velocity, v, is directional. In two dimensions you need to know its angle θ in the x-y plane as well as the elapsed time, t. In that case x =vt cos(θ) and y = vt sin(θ) . In three dimensions its a bit more complicated.
