Use point B to get the centre it's different

Alright. Shall check

The problem is you never get a negative scale factor since you are getting it using the magnitude. So you should always have a simple sketch to help you determine whether the scale factor is negative or positive, otherwise the formula is okay but the scale factor will be -2 and the centre (3,3)
