Final answer:
When a rectangle is translated 1 unit to the right and 4 units up, it moves horizontally to the right side of the coordinate system and vertically upward.
Step-by-step explanation:
When a rectangle is translated 1 unit to the right and 4 units up, it means that each point of the original rectangle is moved 1 unit to the right and 4 units up to create a new rectangle. So, the new rectangle is located horizontally to the right side of the coordinate system and vertically upward in the coordinate system.
