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)

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).
