Question

the graph shows the relationship between a galaxys velocity (in kilometers per second) and its distance (in megaparsecs). this relationship is called hubbles law; more distant galaxies are speeding away more quickly. the points represent individual galaxies and the line represents the best fit to the data. if a galaxy has a velocity of 2625 km/s, what is a good estimate for its distance? distance: mpc

Explanation:

Step1: Locate the velocity on the y - axis

Locate 2625 km/s on the velocity (y - axis) of the graph.

Step2: Find the corresponding x - value

Draw a horizontal line from 2625 km/s on the y - axis until it intersects the best - fit line. Then draw a vertical line down to the x - axis to find the corresponding distance value.

Answer:

35 Mpc
