8.G.A.3 Tutor Intake -- Coordinate Rules for Transformations

This short check helps your tutor see where to start. Work on your own,
without a calculator. Do your best -- the goal is to find what to work
on together, not to grade you.

Concepts

A transformation's coordinate rule is (x, y) to (3x, 3y). Is this
transformation rigid or non-rigid, and why?

Non-rigid -- it multiplies coordinates by 3, which scales (multiplies) all distances by 3

Rigid -- it only involves multiplication, and rigid motions can include multiplication

Non-rigid -- it changes the shape of any figure

Rigid -- the same rule is applied to both coordinates
