It depends on the form of transformation.
it is a translation
Reflection in the line.
It depends on the kind of transformation: it could be reflection or translation.
Translation
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.

Translation.

Reflection in the line.
line transformation ratio would be the turns ratio (ie voltage ratio), while the phase transformation ratio is most probably the phase shift introduced by a 3 phase transformer.
Yes. If it is not straight, then it is not a line.

Displacement of a straight line is zero...
A straight line has no vertex.
it just a straight line
If it is not straight, then it is not a line.
There are 180 degrees on a straight line.
