Question

Write the coordinates of the vertices after a reflection over the line y=
–
x.

Answer 1

see explanation

Explanation:

under a reflection in the line y = - x

a point (x, y ) → (- y, - x ) , then

Q (- 2, - 9 ) → Q' (9, 2 )

R (3, - 6 ) → R' (6, - 3 )

S (- 2, - 3 ) → S' (3, 2 )

T (- 3, - 6 ) → T' (6, 3 )
