Instance
To illustrate you have got a dataset of gross sales figures for a product over the course of a 12 months.
| Month | Gross sales Determine |
| — | — |
| 1 | 100 |
| 2 | 120 |
| 3 | 150 |
| 4 | 180 |
| 5 | 200 |
To make a prediction utilizing the road of greatest match, you would want to create a method that takes under consideration the slope and intercept of the road. Let’s assume the slope is 20 and the intercept is 80. The method could be:
