If the expected relationship you are investigating is likely to be of the form

y = 2.0/(x1/3)

and you plot a graph of log y vs log x what would you expect the value of the slope to be , if the expected relationship is observed?

i think form of the question is y = 2.0/(x^1/3)
so by taking log 
log y=log2-1/3 (logx)
so this is the curve for which you have to find slope
so differentiate both side wrt to x
you would find
(1/y)dy/dx =-(1/3x)
so slope dy/dx =-y/3x
