<h3>Answer: B. 6</h3>

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

Simple...

you have: 8x-6y=1

You're trying to find m-->>using y=mx+b to re-write the line....

8x-6y=1

8x-6y=1
-8x -8x

-6y=-8x+1

$\frac{-6y}{-6} = \frac{-8x+1}{-6}$

y= $\frac{4}{3} x- \frac{1}{6}$

Your slope m= $\frac{4}{3} x$

Thus, your answer.
