The video tutorial explains how to use the line of best fit in a scatter plot to determine the expected population of a bacteria colony after 8 hours. The line of best fit is represented by the equation Y = 2^X. The tutorial demonstrates both graphical and algebraic methods to find the solution, concluding that the expected population is 256. The solution is verified by checking the graph.
