Pitch of net slip and plunge and trend of net slip of a fault using stereonets

[subopolois]

ive been given a problem in my school work. it involves 2 veins that have been cut by a fault and displaced along the fault plane. the question gives the orientation of the cut veins on either side of the wall and the orientation of the fault. it asks for the following: net slip, plunge and trend of the net slip and the attitude of the net slip.

i know how to plot planes, lineations, poles etc on stereonets and i have already found the net slip, i just need some help with the plunge and trend and attitude of the net slip

Maybe this will help.

I would expect the plunge relates to vertical displacement.
