30.1.1 Geometry Does the Bookkeeping: The Idea of Analytic Geometry
Core idea
Lay a shape on grid paper, give every point a street address (x,y), and suddenly you can compute the figure with an equation.
Module goal. Carry the vector thinking forward from the last stage, build the big idea of describing shapes with coordinates and equations, and revisit the tools of the plane.
