For the dilation, do, k = (10, 0) → (5, 0), the scale factor is equal to

The scale factor is .

Step-by-step explanation:

The dilation of a point about the origin with scale factor k is defined as

           ..... (1)

It means the scale factor is calculated as

The given dilation is defined as

               ..... (2)

From (1) and (2) we get,

x coordinate of image = 5

x coordinate of preimage = 10

Therefore the scale factor is .
