The article proposes an interesting construction of a one-to-one mapping of points on a hyperbola branch (as a graph of a fractional rational function) to points on a straight line specified in a suitable coordinate system. Using this construction, various cases of mutual arrangement of hyperbolas of some families (bundles) are explained.
