The equation of the Least Square Regression line which models the data given in the table is : y = 0.26x + 16.9

  • The equation of the Least Square Regression Line can be obtained using technology such as Excel or a linear regression calculator.

The general form of the equation is y = bx + c where ;

  • y = dependent variable
  • x = independent variable
  • b = slope
  • c = intercept

Therefore, the least square regression equation is y = 0.26x + 16.9
