Ответ:
The correct option is (A)![\left(1,-\dfrac{2}{3}\right).](/tpl/images/0373/2038/7d5e1.png)
Step-by-step explanation: We are given to find the co-ordinates of the image of the point R for a dilation with center (0, 0) and a scale factor of![\dfrac{1}{3}.](/tpl/images/0373/2038/9a509.png)
We can see from the given figure that
the co-ordinates of the point R are (3, -2).
Since the figure PQR is dilated with center of dilation as origin (0, 0), so the co-ordinates of the image of point R will be one-third of the co-ordinates of the point R.
Therefore, the co-ordinates of the image of R are
Thus, the co-ordinates of the image of point R are
.
Option (A) is CORRECT.
