Galactic Distance The table lists the distances (in megaparsecs where 1 megaparsec ?3.1 × 1019 km) and velocities (in kilometers per second) of four galaxies moving rapidly away from Earth.

Plot the data points letting x represent distance and y represent velocity. Do the points lie in an approximately linear pattern?________________b. Write a linear equation y = mx to model this data, using the ordered pair 1520, 40,0002.________________c. The galaxy Hydra has a velocity of 60,000 km per sec. Use your equation to approximate how far away it is from Earth.________________d. The value of m in the equation is called the Hubble constant. The Hubble constant can be used to estimate the age of the universe A (in years) using the formula Approximate A using your value of m.
