D' ( , )

Answer 1

A (-1,-4)

B (-5,-8)

C (-5,-4)

D (-4,-2)

Explanation:

Answer 2

A'(-1,-4)

B'(-5,-8)

C'(-5,-4)

D'(-4,-2)

Explanation:

We have been given a graph of a quadrilateral and we are asked to find the coordinates of our quadrilateral after reflecting it across the x-axis.

We can see that coordinates of quadrilateral ABCD are:

A (-1,4),

B (-5,8),

C (-5,4),

D (-4,2).

Since we know that rule for reflecting an image across x-axis is
`(a,b)\rightarrow (a,-b)`. This means that y-coordinates of our given image will be negative.

So after reflecting our given quadrilateral across x-axis, coordinates will be:

`A(-1,4)\rightarrow A'(-1,-4)`

`B(-5,8)\rightarrow B'(-5,-8)`

`C(-5,4)\rightarrow C'(-5,-4)`

`D(-4,2)\rightarrow D'(-4,-2)`
