Given a dilation around the origin, what is the scale factor K?

kobusy [5.1K]

Answer:

The answer is " $\frac{4}{3}$ "

Step-by-step explanation:

Given:

$\bold{DoK = (12, 8) (9,6)}$

In the scale factor when we take x coordinate then the value of k is:

$\Rightarrow x= \frac{x_1}{x_2}\\\\\Rightarrow x= \frac{12}{9}\\\\\Rightarrow x= \frac{4}{3}\\$

If we take y coordinate then the value of k is:

$\Rightarrow y= \frac{y_1}{y_2}\\\\\Rightarrow y= \frac{8}{6}\\\\\Rightarrow y= \frac{4}{3}\\$

So, the final value of k is " $\frac{4}{3}$ " .
