ksitna:
for the invariaant line
well u have to count a certain point
like choose a point and the scale factor u would be given
so if scale factor was 2
and for example in stretch
count how far it is
then for the object
u count how far as well
and when u find a line that satisfies them like if the furthest one was 10
and the object was 5
then that would be the invariant line
hope u got it
