A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marina traced the map onto a coordinate plane to find the exact location of the treasure.
What are the coordinates of the treasure? If necessary, round the coordinates to the nearest tenth.
