Enlarge the shape by scale factor 2, about the origin

Compare the coordinates of the vertices of the image with those of the vertices of the object.

Have a think

Compare the coordinates of the vertices of the image with those of the vertices of the object.

 

 

After an enlargement of scale factor 2 about the origin, the coordinates of the vertices of the image are double those of the vertices of the object.
