# Writing a simple linear regression function

## Question

Write a function that will **read in an arbitrary number of data points (data will be collected from user input in our solution) and return the line of best fit** using linear regression.

*Note: A linear regression line of best fit has the format: y = mx + b, where x is the explanatory variable and y is the dependent variable. The slope of the line is m, and b is the intercept (the value of y when x = 0).*
