There are two regression lines if there are two variables - one line for the regression of the first variable on the second and another line for the regression of the second variable on the first. If there are n variables you can have n*(n-1) regression lines.
With the least squares method, the first of two line focuses on the vertical distance between the points and the regression line whereas the second focuses on the horizontal distances.

Is the line of best fit the same as linear regression?
Linear Regression is a method to generate a "Line of Best fit" yes you can use it, but it depends on the data as to accuracy, standard deviation, etc. there are other types of regression like polynomial regression.
Why is point of intersection of two regression lines median?
It is not.

Can the regression lines be parallel?
Yes.
Why three are two regression lines?
In statistical analysis, there are typically two regression lines when examining relationships between variables in a context involving both dependent and independent variables, or in cases of different groups within the data. For instance, in a simple linear regression, one line represents the relationship between the independent variable (predictor) and the dependent variable (outcome). Conversely, in a multiple regression scenario, a second line could represent an alternate model or subgroup, allowing for comparisons between different categories or to account for additional predictors. Thus, two regression lines can help illustrate the complexity of relationships in the data.
Why are two regression line?
Two regression lines can arise when analyzing data involving two different independent variables (predictors) or when comparing two groups or conditions. For instance, in a multiple regression analysis, one line may represent the relationship between the outcome variable and one predictor, while another line may illustrate the relationship with a different predictor. Additionally, in hierarchical or segmented regression, separate lines may be fitted to different segments of the data to capture varying relationships. This allows for a more nuanced understanding of how different factors influence the dependent variable.

What is regression coefficient and correlation coefficient?
The strength of the linear relationship between the two variables in the regression equation is the correlation coefficient, r, and is always a value between -1 and 1, inclusive. The regression coefficient is the slope of the line of the regression equation.
