If ST is reflected across the line y=x, what is the new coordinate point of S'?
A. (5,2)B. (-5,-2)C. (-2,-5)D. (2,5)
Answer:
B. (-5,-2)
Explanation:
When a point is reflected across y = x, we only need to switch the x and y values of the old coordinates to get the new ones. S is at (-2,-5), so by switching the x and y values, we can find that the S' is at (-5,-2).
