Detailed explanation-1: -When the mean value of the dependent variable is independent of the variation in the independent variable, the slope of the regression line is zero.
Detailed explanation-2: -If the slope of the simple regression equation is equal to zero, the scatter plot for the ordered pairs will be a vertical straight line indicating that there is no relationship between the independent and dependent variables.
Detailed explanation-3: -When the slope of a population regression line equals zero, we conclude that there is a linear relationship between the dependent and independent variables. The slope value for a regression equation represents the average change in the dependent variable for a one-unit increase in the independent variable.
Detailed explanation-4: -In regression analysis, the dependent variable is denoted Y and the independent variable is denoted X. So, in this case, Y=total cholesterol and X=BMI. When there is a single continuous dependent variable and a single independent variable, the analysis is called a simple linear regression analysis .
