(-8, 1) for the last one I believe.

1. Can you rotate the arrow 90 180 or 270 and get the same arrow orientation?
2. This looks like an equilateral triangle.  Therefore each angle is 60 degrees.  Imagine putting a pin in the center of the triangle and rotatiing in 60 degree increments.  Will the triangle realign looking like the original triangle?
3. Only be concerned with Point Y.  Plot this on a coordinate plane.  Calculate the slope from the origin to point Y.  A  90 degree CW rotation will move the point to Quadrant IV.  Therefore the new coordinate will be the same distance from the origin at a perpendicular slope (i.e., opposite reciprical of the one for the origin to point Y).

Meegan's answer would be correct for CCW rotation, not a CW rotation.

what's the last one then? i thought she was right, too. i got the same answer as her):

(8,-1)

anonymous · Answer

A quadrant I point rotated 90 degrees CW will end up in quadrant 4
