What are the coordinates of the image of vertex F after a reflection across the line y= -x
2 answers:
Answer:
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.

Answer:
The correct answer is B.
Step-by-step explanation:
We have the expression:
In this case, B is the correct answer.
B states that any sample point can be chosen without affecting the limit.
This is a true statement. Regardless of which point we choose for our sample point, since n approaches infinity, we will have infinite partitions.
Hence, this will not affect the sum of our expression.
A and C are false because we have infinite partitions, so the statements cannot be true. D is not true simply because the left-hand values do not have to be the same as the midpoint-values depending on the behavior of the function for [a, b].
