Answer:
The 4th one is correct.
Explanation:
On a graph, if a number is negative on the x-axis, you can say that it goes left.
If a number is positive on the y-axis, you can say that it's going up.
So -6 is going left, and +2 is going up.
Now I could be wrong, but I'm sure that the 4th one is the definite answer.
Hope this helps! :)
