Simple linear regression formula y is the predicted value of the dependent variable (y) for any given value of the independent variable (x). B0 is the intercept, the predicted value of y when the x is 0. B1 is the regression coefficient – how much we expect y to change as x increases.

Linear regression is a statistical method used to model the linear relationship between a dependent variable (also known as the response variable) and one or more independent variables (also known as explanatory variables).

The formula is typically represented as Y = aX + b, where Y represents the dependent variable, a represents the slope of the regression equation, X denotes the independent variable, and b represents a constant term.

In simple linear regression, there is only one independent variable, and the line of best fit is a straight line that can be represented by the equation ŷ = a + bx, where ŷ is the predicted value of the dependent variable, x is the value of the independent variable, a is the y-intercept (the value of ŷ when x = 0), and ...

Minus the slope times the mean of the X sample. So once you know B the slope M calculating. The y-intercept is relatively. Straightforward.
