Answer:
Well, if I'm reading this correctly, the answer should be (6,0).
Step-by-step explanation:
It's (6,0) because when you are on the coordinate plane, you would go 6 right on the x-axis, and 4 up, which would give you (6,4). Now, to the part you want to know. You started at (6,4) and you want to go down, just count down below your original point, four times. Then, you should get the answer that I have.
Note:
If I misread the question, just comment and I'll get back to it when I have the time.
