Q:  What is the value of the slope on this graph?  Convert your
            answer to have units of (km/sec) per Mpc.

 
                  slope  is approximately   75 km/s/Mpc



  Q:  How does this value compare to the one based on Hubble's data?


                  Hubble's value:   about 500 km/s/Mpc
                  recent   value:   about  75 km/s/Mpc


         That's a very big difference!  We'll discuss why, and what
         that means, next time.
