Answer:
The correct option is B.
Step-by-step explanation:
It is given that triangle A"B"C" is the image of triangle ABC after transformation.
From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.
It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is
The corresponding sides of image A"B"C" are smaller than the preimage ABC.
Since k<0, therefore the transformation shows the reduction. The dilation rule is
Option B is correct.
