draw a circle in quadrant 2
reflect that into quadrant 3
which axis did you reflect around?
If it were around the negative 45 deg line(y= x), it would never have left quadrant 2
If it were around the positive 45 degree line (y=x) it would have jumped int quadrant 4
If it were around the y axis, it would have moved right into quadrant 1
So, it went the x axis route, down into quadrant 3
