The equation $y = b_0 + b_1x$ algebraically describes the linear regression relationship between the two variables $x$ and $y$. Here:

• $y$ is the dependent variable (the variable you're predicting),
• $x$ is the independent variable (the variable you're using to predict),
• $b_0$ is the intercept (the value of $y$ when $x = 0$),
• $b_1$ is the slope (which represents the change in $y$ for a unit change in $x$).

This is a simple linear regression equation that models the relationship between two variables. The goal of linear regression is to find the best-fitting line (the line that minimizes the sum of squared differences between observed and predicted values).

Tip: In linear regression, the least squares method is typically used to find the values of $b_0$ and $b_1$ that minimize the residual sum of squares.
