Help anyone please!!!

Hi

mathmate · Answer

Hints:
In a dilation, all angles and orientations are preserved if the scale is positive.
If the scale is negative, the orientations are reversed.

chillydog0 · Answer

Ok. I believe the answer is D.

Sorry, I do not work with letter answers, because it devalues the answer.
Also, I do not validate unelaborated answers, because they might be guesses.

chillydog0 · Answer

Ok. Then I believe that it shifts 5 units to the right because when it dilates it reverses. (Negative to positive) (Positive to Negative)

@Chillydog0 
Sorry, I do not know if you are aware of it, but I am unable to view the link you provided.  It requires a login,  so I do not get to know the scale of the dilation, nor the position and size of the objects, which I need if you believe your answer is the line that shifts 5 units.
You can help by posting an image of the question at an image server, or draw a sketch to describe the situation.

Tada

mathmate · Answer

Thank you for posting the image.
Please explain why it is a horizontal shift of 5 units and not 7 units.

chillydog0 · Answer

Well for one that is not on the questions. For two it does not make sense to shift it that far.  
OP/OP=K

mathmate · Answer

I think you meant OP'/OP=K.
So what is the value of K, and where is O situated?

chillydog0 · Answer

I don't know I am a little confused about this whole situation.

mathmate · Answer

Excellent. 
When you are confused, the best remedy is to read the course material.
If you have read the course material and could still use further help, read what I posted, and read the link I proposed.
Please tag me when you're done with the reading.
