To rotate the point Q(-5, -9) by -270° (which is equivalent to a 90° clockwise rotation) around the origin, we can use the rotation formula for a 90° clockwise rotation:
If you have a point (x, y), after a 90° clockwise rotation, the new coordinates (x', y') will be: \[ (x', y') = (y, -x) \]
For the point Q(-5, -9):
- x = -5
- y = -9
Applying the rotation formula:
- x' = y = -9
- y' = -x = -(-5) = 5
Therefore, the new coordinates after the rotation are Q'(-9, 5).
However, to find the answer that is presented in the choices: We can check the available options against the calculated point:
- Q' (9, -5)
- Q' (9, 5)
- Q' (5, 9)
- Q' (-5, 9)
None of these options seem to match the calculated Q'(-9, 5). Thus, make sure to double-check for any possible mistakes; however, based on the calculation, the result for Q after a -270° rotation (i.e., 90° clockwise) should indeed be Q'(-9, 5).
If you understand the concept and have the finalized coordinates, please clarify or adjust, as it seems there may have been a mismatch in the calculation versus the options presented.
