Doesn't seem like there's enough information to answer the question.
Are you giving the x,y coordinates in 2 dimensional space, or are they x,t coordinates with the times converted to distances ?
More information needed in any case.

anonymous · Answer

If the first coordinate represented time, in units of distance with the speed of light as the conversion factor, and the second coordinate represented distance, then an object moving along the x axis from event A to event B would have a velocity of -2/5 the speed of light.

But that might not be the correct interpretation of your coordinates : (
