b. (2.5, 5.95)
residual =

c. (0, 3.72)
residual =

d. (1.5, 5.05)
residual =

e. (-3, 0)
residual =

f. (-5, -4.86)
residual =

Explanation:

To calculate the residual, we use the formula:
Residual = Observed value - Predicted value.

However, the problem is missing the regression equation (or predicted value function) to find the predicted value for each \( x \)-value. Without the regression equation, we cannot compute the predicted \( y \)-value for each point, so we cannot calculate the residual.

Please provide the regression equation (e.g., \( \hat{y} = mx + b \)) or the method to find the predicted value for each \( x \)-coordinate.
