21.4.5 Recovering the Formula from Properties or a Shift

Core idea

Clues like "parallel to a certain line" or "passing through a certain point" turn into equations in k and b that you solve.

Module goal. Master the general technique for recovering y=kx+b from given conditions, opening the reverse route from "graph or data" back to "formula."
