Answer:
see attached
Step-by-step explanation:
Each point moves to 3 times its original distance from P.
That movement is indicated by the blue arrows in the attachment. The dilation of the upper left corner and lower right corner are shown. Both the number of horizontal grid squares and the number of vertical grid squares are multiplied by 3. (This factor of 3 applies both to distance from P and to image size.) Each image segment is 3 times as long as the original.
