Simple linear regression is used to quantify the relationship between a predictor variable and a response variable. This method finds a line that best “fits” a dataset and takes on the following form: ŷ = b 0 + b 1 x. where: ŷ: The estimated response value; b 0: The intercept of the regression line; b 1: The slope of the regression line

slope: the amount the response variable (y) changes for every unit increase in the explanatory variable (x) y-intercept: the value of the response variable (y) when the explanatory variable (x) is 0. It’s where the least-squares regression line crosses the y-axis. The equation of the least-squares regression line is: \ ( \hat {y}=a+bx \) ,where.
