How can I calculate the slope from a linear regression analysis?

WebMar 31, 2024 · The formula y = m*x + b helps us calculate the mathematical equation of our regression line. Substituting the values for y-intercept and slope we got from extending the regression line, we can formulate the equation - y = 0.01x — 2.48 -2.48 is a more accurate y-intercept value I got from the regression table as shown later in this post. WebApr 11, 2024 · Linear regression is a method for predicting y from x. In our case, y is the dependent variable, and x is the independent variable. We want to predict the value of y for a given value of x.
