Correct Answer

D. (6)

Step 1

Concept

\(y=\frac{30}{k}x-\frac{90}{k}\). From \(-\frac{90}{k}=-15\), (k=6).

Step 2

Why this answer is correct

The correct answer is D. (6). \(y=\frac{30}{k}x-\frac{90}{k}\). From \(-\frac{90}{k}=-15\), (k=6).

Step 3

Exam Tip

\(y=\frac{30}{k}x-\frac{90}{k}\) होगा। \(-\frac{90}{k}=-15\) से (k=6) है।
