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
![(x,y)\rightarrow (x,-y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28x%2C-y%29)
The coordinate of point D are (-1,5).
The coordinates of point D after reflection across x-axis are
![D(-1,5)\rightarrow D'(-1,-5)](https://tex.z-dn.net/?f=D%28-1%2C5%29%5Crightarrow%20D%27%28-1%2C-5%29)
The x-coordinate of D' = -1
The y-coordinate of D' = -5
Therefore the correct options are 3 and 4.
