Given:
A coordinate pair was dilated from (-3, 2) to (-6, 4).
To find:
The scale factor.
Solution:
We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.
The value of scale factor is:
[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]
[tex]k=\dfrac{-6}{-3}[/tex]
[tex]k=2[/tex]
Therefore, the scale factor is 2.
