Explanation:

Correct option is A)

Let Q(h,k) be the image of P(3,3) w.r.t the line mirror x+y=0

a

h−p

=

b

k−q

=

a

2

+b

2

−2×(ap+bq+c)

1

h−3

=

1

k−3

=

2

−2(6)

⇒h−3=k−3=−6

⇒h=−3,k=−3

So, the image is Q(−3,−3).

In the second transformation, point Q is translated horizontally 3 units to the left and vertically 3 units up.

So, the coordinates of new image is (−3−3,−3+3) i.e. (−6,0)

In the third transformation, point (−6,0) is reflected w.r.t the line y=x

So, the final image is (0,−6).
