Laura, think about the direction you would be going with respect to each axis.
For point (x,y) if x>0 then you would be going in the positive direction on the x axis. This eliminates quadrants II and III because the x axis is negative there. Now you're down to either quadrant I or quadrant IV. Given that y<0, the y values on the y axis are less than 0 so they are becoming negative. This means that (x, y) must be in quadrant IV!
If you forget what quadrants are where, remember that if (x, y) are both positive that's quadrant I and the quadrants are numbered counter clockwise
