Answer:
The correct options are 3 and 4.
Step-by-step explanation:
Given information: Point D ( −1, 5 ) is reflected across the x-axis.
If a point reflected across x-axis, then
The coordinate of point D are (-1,5).
The coordinates of point D after reflection across x-axis are
The x-coordinate of D' = -1
The y-coordinate of D' = -5
Therefore the correct options are 3 and 4.
