help me explain simple linear regression (SLR), along with multiple regression analysis. A simple linear regression shows a linear relationship between data points using a regression line. It helps to better understand and predict the relationship between two variables. For example: a linear regression line can be shown for a job position that the more years of experience you have the higher your salary. However, the regression line shows predictions, there can be data points that lay above or below, or do not even lay near the line. A multiple regression is a way to model the linear relationship between one quantitative response variable and more than one predictor variable
