This is a graph of Edwin Hubble's original data. The gradient of this graph is called Hubble's constant. It has units of ${\mathrm{kms}}^{-1}{\mathrm{Mpc}}^{-1}$..

Find the gradient of this graph.

This is a graph of Edwin Hubble's original data. The gradient of this graph is called Hubble's constant. It has units of ${\mathrm{kms}}^{-1}{\mathrm{Mpc}}^{-1}$.

 Comment on the reliability of the trend.

This is a graph of Edwin Hubble's original data. The gradient of this graph is called Hubble's constant. It has units of ${\mathrm{kms}}^{-1}{\mathrm{Mpc}}^{-1}$..

Find the gradient of this graph.

The accepted value of Hubble's constant is $72 {\mathrm{kms}}^{-1}{\mathrm{Mpc}}^{-1}$ What does this suggest about the validity of Hubble's original experiment?
