Simple Linear Regression Step by Step

Simple linear regression in machine learning is a method used to find a straight line that best fits a set of data points. Think of it like drawing a line through a bunch of dots on a graph to show a trend or relationship.

Here’s a simple breakdown:

What It Does: Linear regression tries to predict a value (like the cost of a pizza) based on another value (like the size of the pizza). If you have data showing pizza prices based on size, linear regression can help find the "best-fit" line that shows this relationship.

Goal: Linear regression finds the values of m and b so that the line goes through the data points as closely as possible. This line can then help make predictions based on new values of x
