Is it appropriate to use the line of best fit to make the prediction for Tigger? No, because it is not appropriate to use a linear model for this dataset. No, because Tigger's weight is outside the range of data values used to make the linear equation, and this is an example of extrapolation. Yes, because overall the dataset follows a linear trend and Tigger's weight is inside or close enough to the range of data values used to make the line of best fit. This is an example of "interpolation" which is a good statistical practice
