Question

The triangle shown is dilated with scale factor =1/2 which is the image of vertex s after the dilation

Answer 1

The dilation factor is 1/2. This means the image would be half to the pre-image.

The coordinates for S are (2,4). So, its image is

`((1)/(2)\cdot2,(1)/(2)\cdot4)=(1,2)`

Therefore, the right answer is the first choice.
