22.5.5 Looking Back: The Rate of Change Is No Longer Constant

Core idea

A line changes at a constant rate while a hyperbola eases off the farther it goes, quietly setting the stage for the curving parabola coming next.

Module goal. Use the inverse-proportion model to describe real quantities whose product stays fixed, building the model, solving it, and respecting the limits on the domain.
