In science and engineering, a log-log graph or log-log plot is a way of visualizing data that is changing with a power law. Both horizontal and vertical axes are plotted on a logarithmic scale. All functions of the form $y=ax^b$ form straight lines (where b determines the slope and a determines the x=1 intercept), since taking logs of both sides is equal to

$\backslash log(y)\; =\; b\backslash log(x)\; +\; \backslash log(a)\backslash ,\backslash !$
