The question asks about number of points reflected across y=x with integers ranging from -10 to 10 for x and y.so if a point which needs to be reflected across y=x must have the same magnitude and sign.If we look more into it all the points which have same magnitude and sign for both x and y lie ON THE LINE.so how is that it will be reflected across the line?what m I missing?
When you reflect points ON the line you just get the same as the result right? I assume in this question that does count as a reflection
The question clearly says reflected ACROSS the line so that contradicts what the we got as an answer.Can you shed some light on how can the points lie across the line when they are ON the line?
@Leaderboard can you read the user’s feedback and make changes to the question if you feel its necessary?
Does “across” necessarily imply that the points must be different, when the question clarifies that they are the same?
Just sharing my sharing my 2 cents here, from what I infer from the question is if it reflects its not on the line.Correct me if I’m wrong or if its mentioned in some of the official ETS guidelines or book.
We’ll get back to you.
The question has been slightly adjusted to resolve these concerns.
