Let \(\alpha\), \(\beta\) and \(\gamma\) be real numbers such that the system of linear equations
x + 2y + 3z = \(\alpha\)
4x + 5y + 6z = \(\beta\)
7x + 8y + 9z = \(\gamma\) \(-\) 1
is consistent. Let | M | represent the determinant of the matrix
$$M = \left[ {\matrix{ \[\alpha & 2 & \gamma \cr\] \[\beta & 1 & 0 \cr\] { - 1} & 0 & 1 \cr } } \right]$$
Let P be the plane containing all those (\(\alpha\), \(\beta\), \(\gamma\)) for which the above system of linear equations is consistent, and D be the square of the distance of the point (0, 1, 0) from the plane P.
The value of | M | is _________.
