What are the coordinates of the image of vertex f after a reflection across the line y= -x

B.

Step-by-step explanation:

We have been given an image of a quadrilateral. We are asked to find the coordinates of the image of vertex F after a reflection across the line .    

We know that rule of reflection across the line is .

We can see that coordinates of point F are .

After reflecting point F across the line , the x- and y-coordinates will interchange their place and their signs will be changed as well.

Therefore, the coordinates of the image of vertex F after a reflection across the line are and option B is the correct choice.

can you add an image ?

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
