12.9 Solutions to Least Squares Problems

    1. y = 3 - 1.5x
      Sum of squared errors = 0

      graph of the line

    2. y = 3.3 - 1.5x
      Sum of squared errors = 0.67

    graph of the line

    1. y = 3.2 - 1.6x
      Sum of squared errors = 1.2

    graph of the line

  2. y = 5.8 - 1.2x

  3. y = 0.1 + 3x

  4. y = 0.13 - 1.29x + 3.31x2
    Sum of squared errors = 0.12

  5. y = 3.23 - 1.90x + 0.79x2

  6. Linear model: 5.5811 + 1.9054x
