Would my answer be correct?

Sunita performed a transformation on trapezoid LMNQ to create L′M′N′Q′, as shown in the figure below:


A four quadrant coordinate grid is drawn. Trapezoid LMNQ with coordinates are drawn at L negative 7, negative 2. M is at negative 5, negative 2. N is at negative 3, negative 4. Q is at negative 8, negative 5. Trapezoid P prime Q prime R prime S prime with coordinates are drawn at L prime negative 2, 7. M prime is at negative 2, 5. N prime is at negative 4, 3. Q prime is at negative 5, 8.


What transformation did Sunita perform to create L′M′N′Q′?

 Rotation of 90° counterclockwise about the origin

 Rotation of 270° counterclockwise about the origin 

Reflection across the x‒axis

 Reflection across the line of symmetry of the figure I say option 2 but I am not sure please correct me!

Write down the points associated with LMNQ and the points associated with L’M’N’Q’ to see which situation they fit , did you switch x and y and make y negative, did you switch x and y and make x negative, or if they fit another situation.

I believe that the better choice is "rotation of 90 degrees counterclockwise". Your selection would be correct if it was 270 degrees clockwise. Perhaps the only thing you are unsure of is the terms clockwise versus counterclockwise? Look at the numbers on an analog clock. The direction they count : 1, 2, 3, 4, ....that is CLOCKWISE
