Answer:
[tex]M (x,y)= M'(y,x)[/tex]
Step-by-step explanation:
The coordinates of M' after two geometric transformations of reflection across the y axis, and then rotation having (0,0) the center of rotation as doing it clockwise is mapped through this rule:
[tex]M (x,y)= M'(y,x)[/tex]
1) Reflecting across y-axis (check the 1st picture)
2) Rotating 90º having (0,0) as the Center of Rotation.
