Do, k = (6, 12) → (3, 6) the scale factor is 1/2 2 4

The scale factor of given coordinate

A is correct.

Step-by-step explanation:

We are given two coordinate O and K. The dilation with respect to origin.

For scale factor,

a is scale factor of coordinate.

If we divide new coordinate with old coordinate to get scale factor.

Hence, The scale factor of given coordinate

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

step-by-step explanation:

this is not a question
