Which rule describes a composition of transformations that maps pre-image PQRS to image P"Q"R"S"?
2 answers:
Answer:
Reflected across the y-axis composition 270 degree rotation about point O
Step-by-step explanation:
The transformation appears to be ...
(x, y) ⇒ (-y, -x)
__
Rotation 270° about the origin results in the transformation ...
(x, y) ⇒ (y, -x)
and reflection across the y-axis is the transformation
(x, y) ⇒ (-x, y)
The composition of these two transformations is the one we're looking for:
(x, y) ⇒ (-y, -x)
The rule of interest is 270° rotation about the origin followed by reflection across the y-axis. Written as a composition, this might be ...

If M is a midpoint of PQ, then we can use the formula of a midpoint:
We have the endpoints (-2a, 0) and (0, 2b). Substitute:
