What is the name of the technique that create this graph

You have 1 ml of kombucha. You remove 0.1 ml of this and mix it with 9.9 ml of fresh tea. You mix the second tube, then remove 1 ml of this mixture and add it to 9 ml of fresh tea. You then mix this, and remove 0.1 ml of this solution, and plate it. The next day, you return to find 362 colonies. What was the concentration of the cells in the original mix? Show your calculations.  My professor worked this problem out in class but she used a different method than that from the Khan academy videos on youtube and I am getting lost in the steps. Do you mind labeling?

How will this look drawn in?

On the graph that relates absorbance to flavin concentration, draw a horizontal line that starts at the point on the y-axis that corresponds to the absorbance of your unknown sample and ends at the curve you drew through your data points . Next draw a vertical line that starts at the point where the horizontal line intersected the curve and ends at the x-axis. The point where this vertical line intersects the x-axis corresponds to the concentration of flavin in your unknown sample. What was the letter on the tube with your unknown sample? What is the concentration of the flavin in your unknown
