7. Plot the speed of each galaxy in Table 1 on the y-axis and the distance to the galaxy on the x-axis. Draw a line of best fit. 6000 5000 4000 Speed (km/s) 3000 2000 1000 0 o 5 10 15 20 25 Distance (x 1020 km) 8. Calculate the slope of the line. What is the unit for the slope? 9. The slope of this line is called the Hubble constant, Ho. Write the equation for this line using He as your slope. What does it tell you about the relationship between the speed of galaxies and their distance? This relationship is called Hubble's law. 10. The age of the universe, T, can be approximated by taking the reciprocal, or inverse, of Ho. Take the reciprocal of your slope. How old is the universe (in years)?
