Q: What does IP AMaths Notes (Upper Sec, Year 3-4): 03) Linear Law cover?
A: Transform non-linear relationships into straight lines for graph paper work and regression checks in IP AMaths.

Linear-law questions ask you to recast a model so plotting gives a straight line. Identify the transformation, compute plotting coordinates, and interpret the resulting gradient and intercept.
