Answer:
Quadrant II.
Step-by-step explanation:
Starting in the top right quadrant and going counter-clockwise, the quadrants are labeled Quadrant I, Quadrant II, Quadrant III, and Quadrant IV (each quadrant being a quarter of the graph area of course). So, x being negative puts the point to the left, and y being positive puts the point up. Quadrant II is the top-left quadrant, so it is our answer.
Positive 3, If You're starting at -6 and you add the first 6 it's at 0, now you have 3 more to add to make 9. And that gives you positive 3. or if you do 9 - 6 you can get your answer that way too.
