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

Find the gradient of this graph.

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