Frequently Asked Questions
Linear regression is used to model the relationship between a dependent variable ($y$) and an independent variable ($x$) by fitting a linear equation to observed data.
The line of best fit is the straight line that minimizes the sum of squared differences between observed values and values predicted by the model.
Yes. Once the equation $y = mx + b$ is found, you can substitute any value of $x$ to predict the corresponding value of $y$.
