This is because if the observed data points are close to the regression line, it indicates that the model is accurately capturing the underlying relationship between the variables, and therefore can be used to make more accurate predictions. On the other hand, if the data points are far away from the regression line, it suggests that there may be unaccounted for factors affecting the relationship between the variables, and the model may have lower predictive accuracy.
