Answer :

The scale factor is a factor that affects coordinate x and y of all the points in an image, using one of the points of th preimage and the image we can find the realtion between both

[tex](2,3)\rightarrow(4,6)[/tex]

if we analyse this the scale factor is 2, since both x and y coordinate are doubling the pre image.

Also if we analyse the other 2 points the same happens.
