For those whose algebra is rusty: Let y = ax^n Then log(y) = log(ax^n) = log(a)+log(x^n) = log(a) + log(x)*n i.e. and equation for a line when plotting log(y

For those whose algebra is rusty: Let y = ax^n Then log(y) = log(ax^n) = log(a)+log(x^n) = log(a) + log(x)*n i.e. and equation for a line when plotting log(y) vs. log(x).
