Caption: "A log-log plot of the power-law function f(x) = [x**(-10)]*[(10**(20)], which in logarithmic form is log[f(x)] = -10*log(x) + 20.

In this log-log plot, the powers of 10 are shown.

In many log-log plots, just the powers are shown.

If just the powers were shown for this plot, the x-axis values would run 0, 1, 2, 3 and the y-axis values would run -20, -15, -10, -5, 0, 5, 10, 15, 20.

The logarithmic form, the y-intercept is 20 and the slope is -10.
