To solve the problem provided in the image, let's follow these steps for regression line calculations:

1. **Extract Data from the Graph**: The points on the graph need to be identified. For example:
   - If the points are: (x, y) = (2, 9), (4, 6), ..., list all 10 pairs.

2. **Find the Equation of the Regression Line for All 10 Points**:
   - Use the formula for a linear regression line: 
     \[
     \hat{y} = b_0 + b_1x
     \]
     where:
     \[
     b_1 = \frac{n\sum(xy) - \sum x \sum y}{n\sum(x^2) - (\sum x)^2}
     \]
     \[
     b_0 = \frac{\sum y - b_1\sum x}{n}
     \]
   - Calculate these values based on the 10 points.

3. **Remove the Point (2, 9)**:
   - Recalculate the regression line using the remaining 9 points.

4. **Compare Results**:
   - Compare the slopes (\(b_1\)) and intercepts (\(b_0\)) from both equations.

If you'd like, I can process the exact calculation steps for you, but I'll need either the full list of points or confirmation that you want me to manually estimate them from the graph. Could you confirm or

Using the pairs of values for all 10 points, find the equation of the regression line. After removing the point with coordinates (2, 9), use the pairs of values for the remaining 9 points and find the equation of the regression line. Compare the results from parts (a) and (b).
