Answer:
D. Stretch
Step-by-step explanation:
A rigid motion leaves the size and shape the same there for a stretch is a non-rigid transformation because changes the shape.
All the others keep the same dimensions
6y=12x+18
Y=Mx+b
6/6
6/6 not equal -1/1 so these lines intersect each other at only one point hence these have only one solution.
