How to Write Coordinate Notation for Dilations

Miacademy & MiaPrep Learning Channel

This instructional video provides a clear, step-by-step guide on how to write and interpret coordinate notation for geometric dilations centered at the origin. The lesson bridges the gap between visual transformations on a graph and their algebraic representations, showing students exactly how coordinates change when a shape is resized. It systematically covers four different types of problems: writing notation from given points, finding image coordinates given a rule, finding pre-image coordinates by working backward, and calculating the scale factor to determine the notation.
