M1 · The Best Straight Line
Curves From a Linear Model
Add polynomial features to fit a curve, and explain why the model is still linear.
Britain's Highway Code prints how far a car needs to stop. At 20 mph, 12 meters. At 70 mph, 96. Speed went up three and a half times. Stopping distance went up eight times. Fit a straight line anyway. From a distance it looks fine. The sticks say otherwise.
