One way to define a hyperbola is:
Pick any two points. These are the foci. Now pick a number, call it "a". The hyperbola is the set of all points (x,y) in a plane such that the difference of the distances (x,y) to the foci is a constant number. Given the coordinates (x1,y1) and (x2,y2) of the foci, and having picked the difference in distance "a", you can use the Pythagorean theorem to get an equation for a particular hyperbola:
a=sqrt[(x-x1)^2+(y-y1)^2]-sqrt[(x-x2)^2+(y-y2)^2].

y = k/x - this is for plain shape,
where k is a number.
