Regression allows us to ask useful questions of our data, such as: 
1. Is there a relationship between `\(y\)` and `\(x\)`? 
2. How strong are these relationships? 
3. How can `\(y\)` be predicted for certain values of `\(x\)`? 
4. How well can the model be used to predict `\(y\)` when new data are used?
