What are the common mistakes in Enlargements Positive Scale Factor?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Adds the scale factor to a length instead of multiplying by it

  The scale factor multiplies the distance from the centre - it should not simply be added to the coordinates.

• Enlarges from the origin instead of the stated centre of enlargement

  The enlargement must be measured from the given centre (-1, 0), not from the origin.

• Uses the reciprocal of the correct scale factor

  The image is larger than the original, so the scale factor is 2, not a fraction less than 1 - a fractional scale factor would make the image smaller.
