# Python | Numpy polynomial legline() method

`np.legline()` method is used to find a Legendre series whose graph is a straight line.

Syntax : `np.legline(off, scl)`
Parameters:
off, scl :[scalar] The specified line is given by off + scl*x.

Return : [ndarray] Legendre series coefficient array for the resulting line.

Code #1 :

Output:

```[2 3]
```
