### Handwritten Notes from Math Class

#### Topic: Regression Analysis

**Main Concept:**
- An outlier is an influential point if the regression line changes a lot after removing it from the regression model.
  - **Question: Is this true or false about an outlier?**

**Additional Notes:**
- The area of a circle
- Mathematical equation: \( (x + 2y)^2 - 36 \)
- Possible steps or solutions: find the answer
- Various calculations with values such as 85, 22, 105, 5/7
- Mentions of problem-solving methods:
  - Helpful hints
  - Evaluation of \( x \)
- Related notes on steps to finding answers and assessing solutions

These notes appear to pose a question related to the impact of outliers on regression analysis, urging students to consider whether an influential point can significantly alter a regression model when removed. Additional unrelated calculations and problem-solving steps are also noted.
