1. ## transformation

A quarter turn is a 90 degree rotation. If the counterclockwise quarter-turn centered at (3,2) is applied to (7,1) what are the coordinates of the image? What are the image coordinates when this transformation is applied to a general point (x,y)?

I have (4,6) but i can't get the second one.

Pls find attached work.i have found a vector pattern for the transformation

A quarter turn is a 90 degree rotation.
If the counterclockwise quarter-turn centered at (3,2) is applied to (7,1),
. . what are the coordinates of the image?
What are the image coordinates when this transformation
. . is applied to a general point (x,y)?

We have the point $A(3,2)$ and any point $P(x,y)$

Code:
```      |                 y-2
|             Q * - - *
|                     :
|                     :
|                     : x-3
|                     :
|                     :
|                     :P
|                     *(x,y}
|                 *   :
|             *       :y-2
|         *           :
|   A * - - - - - - - *
|   (3,2)   x-3
--+------------------------

Going from $A$ to $P$, we move $x\!-\!3$ units right and $y\!-\!2$ up.

Going from $P$ to $Q$, we move $x\!-\!3$ units up and $y\!-\!2$ left.
. . (I hope you understand why.)

Therefore, point $Q$ is at: . $(x\!-\!y\!+\!2,\:x\!+\!y\!-\!3)$
