Question

The image of point (3, 2) under the operation $M_o.M_y$ is

• A. (-3, 2)
• B. (3, 2)
• C. (-3, -2)
• D. (3, -2)

Answer 1

The correct option is D

(3, -2)

$M_o$ is reflection of the point (3, 2) in the origin which is (-3, -2).

Next is $M_y$ is the reflection of the point (-3, -2) in the y axis - which is (3, -2).

$\therefore$ The image of point (3, 2) under the operation $M_o.M_y$ is (3 , -2)
