Question

What is the scale factor of a pair of figures whose preimage has coordinates(2, 3), (3, 1), and (4,5), and whose image has coordinates (4, 6), (6, 2), and (8, 10)?

Answer 1

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

If we analyze this, the scale factor is two since both the x and y coordinates are doubling the pre-image.

Also, if we analyze the other 2 points, the same happens.

Explanation:

Answer 2

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

`(2,3)\rightarrow(4,6)`

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.
