Answer:
i dont understand?
Step-by-step explanation:
Given:
The point is (-12,-8).
Rule of transformation is
.
To find:
The coordinates of image after transformation.
Solution:
According to the rule of transformation
, first the point is dilated by factor
with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
If a point is dilated by factor
with origin as center of dilation, then
If a point is rotated 270 degrees anticlockwise, then
![(x,y)\to (y,-x)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%28y%2C-x%29)
![(-3,-2)\to ((-2),-(-3))](https://tex.z-dn.net/?f=%28-3%2C-2%29%5Cto%20%28%28-2%29%2C-%28-3%29%29)
![(-3,-2)\to (-2,3)](https://tex.z-dn.net/?f=%28-3%2C-2%29%5Cto%20%28-2%2C3%29)
Therefore, the coordinates of image after transformation are (-2,3).
