# Linear Regression

## Simple Linear Regression

- A model has one feature of data
- $y = w_0 + w_1*x$

## Multiple Linear Regression

- A model has several features of data
- $y = w_0 + w_1*x + \dots + w_D*x_D$ 

## Polynomial Regression

- A model has increased degrees of features
- $y = w_0 + w_1*x + w_2*x^2 + w_m*x^m$
