To find the residual of a data point, you need to calculate the difference between the observed value and the predicted value from the model at that specific input.
The formula for the residual is:
\[ \text{Residual} = \text{Observed value} - \text{Predicted value} \]
In this case, the observed value is \(15.27\) (the y-value of the point) and you need the predicted value from a model for the input \(x = 2\). If you have a specific model (like a linear regression equation), you can use that model to compute the predicted value.
Since you haven't provided a specific model, I can't compute the predicted value for \(x = 2\). If you provide that model, I can help you calculate the predicted value and then determine the residual.
Please provide the model or the predicted value for \(x=2\) so that we can complete the calculation.
