Dear katherine. You ask a new question, which is not related to this
one. Please post it as a new question. Answer to your question is the
following: rotation of 270 degrees counterclockwise moves point (x,y)
to (y,-x). Therefore, the coordinates of the vertices will be (4,1),
(3,-8), (-1, -4).

The vertices of / are K(–1, 4), L(8, 3), and M(4, –1). / is
rotated 270° counterclockwise about the origin to form /. What are
the coordinates of the vertices of /?
