The coordinates of point P on a coordinate grid are (?5, ?6). Point P is reflected across the y-axis to obtain point Q and across the x-axis to obtain point R. What are the coordinates of points Q and R? 1. Q(5, 6) and R(?5, ?6) 2. Q(?5, ?6) and R(5, 6) 3. Q(?5, 6) and R(5, ?6) 4. Q(5, ?6) and R(?5, 6)
