Consider a 'power-law relationship' where the power-law index, r , and the constant of proportionality, c , are both unknown.
If you had collected data relating x and y (and you expect it to follow the relationship above), then which of the following would be a way to linearise that data such that you could make a graph where r should be the gradient?

Answer

Graph    vs    (where "log" is "logarithm to base 10")

Answer

Graph    vs    (where " ln " is the "natural logarithm" or the "logarithm to base e")

Answer

Graph    vs

Answer

There is not enough information to linearise this data for a graph, because we do not know the constant of proportionality,  c.

Answer

There is not enough information to linearise this data for a graph, because we cannot untangle the 'power of  r ' on the right-hand side of the equation.

Graph    vs
