To estimate the shoe size for someone who is 82 inches tall using the line of best fit from the scatter plot, you would need to refer to the graphical representation directly. If the exact line of best fit is not visible or the scatter plot is not provided in text form, I cannot directly analyze the graph.
However, generally speaking, you would find the height of 82 inches on the x-axis of the scatter plot and then locate where that intersects with the line of best fit. You would then move vertically to the y-axis to find the corresponding estimated shoe size.
If you provide me more details about the scatter plot or how the line of best fit appears, I could help you interpret it or guide you through estimating the shoe size. Without that, you'll need to determine the shoe size using the scatter plot directly.
