Question

In the graph below, line k with equation y = -k makes a 45° angle with the x- and y- axes. Complete the following: Rx Rk : (2,5)

A. (-2, -5)
B. (-5, 2)

Answer 1

A reflection across the line y= -x (which is what this is) means that each point gets reflect such that (a,b) becomes (-b,a).
In this case, (a,b) is (2,5).
The means the correct answer is
(-5,-2)

There may be a transcription error, but this is the answer
