What does invariant line- y axis mean? How to find the matrix of shears and stretches without memorising?

I know that invariant line- y axis means that the stretch or shear is parallel to the x axis - but what does that mean??
 
Also, how can i use base vectors to find the matrix of shears and stretches without having to memorise them?
 
Thanks a lot!
