Answer:
On the y-axis
Explanation:
1. You have to locate where the x and y axis goes to.
2. Locate where the number is on the x-axis. Since your number is 0, it stays where it is right now
3. Locate where the number is on the y-axis. Your number is 9 so it would go up 9 on the y-axis.
There is your answer. Coordinate (0,9) is located on the y-axis of a coordinate graph.
