Answer:
Horizontal
Step-by-step explanation:
Horizontal lines are mostly associated with peace and rest. Think about a calm ocean or lake. It is peaceful when the waves are small and smooth, or flat. The water seems calm, quiet, and peaceful. Think about when you sleep. Most of the time when we lie down, it is on a flat surface, like a mattress.
Curved lines portray motion and action, like rolling waves and stormy seas, giving the feeling of rising and falling, hills and mountains.
