1. Neither
2. reflection over the x -axis
3. reflection over the y -axis
Explanation
The rule for a reflection over the x -axis is (x,y)→(x,−y)
The rule for a reflection over the y -axis is (x,y)→(−x,y)
1. B (-3,-7) B' (-7,-3) neither, this does not fit either rule
2. D (5,-8) D' (5,8) the y changes from -8 to + 8 so reflection over the x -axis
3. F (10,0) F' (-10,0) the x changes from +10 to -10 so reflection over the y -axis
