# Linear Regression-method of prediction

**Linear Regression** is the analyses of two separate variables to define a single relationship. In this, we predict one variable depending on the other variable.

The factor which we predict is known as **Dependent Variable** and other is **Independent Variable.**

We will try to understand this relationship with an example of Car's speed and Car's mileage.

Here, car's mileage is a depending variable and will denote it with 'Y' and car's speed is an independent variable and will denote it with 'X'.

Car's Speed(miles per hour-X) Car's Mileage(miles per gallon-Y)

The graph will show BEST FITTED LINE which means this is closest prediction with minimum error:
