On a coordinate plane, a triangle is shifted up.
On a coordinate plane, a triangle is shifted to the left.
On a coordinate plane, a triangle is enlarged to form another triangle.
On a coordinate plane, a triangle is shifted up and to the left.

Answer 1

"On a coordinate plane, a triangle is shifted up."

This is the only option that represents a purely vertical translation (x-coordinates unchanged, y-coordinates increased).
