Consider the graph of the line of best fit, y = 0.5x + 1, and the given data points.
2 answers:
The residual value is the vertical distance between the observed value and the predicted value. In other words,
residual value = point in scatter plot - point in the line of best fit
When , the corresponding scatter plot point is at
and the corresponding point in the line of best fit is
[can be seen from the graph]
Hence,
residual value = . Answer choice B is correct.
