Correct Answer

B. (y=72-6x)

Step 1

Concept

The rate is (-6), and (a-6(5)=42) gives (a=72). So (y=72-6x) is correct.

Step 2

Why this answer is correct

The correct answer is B. (y=72-6x). The rate is (-6), and (a-6(5)=42) gives (a=72). So (y=72-6x) is correct.

Step 3

Exam Tip

दर (-6) है और (a-6(5)=42) से (a=72) मिलता है। इसलिए (y=72-6x) सही है।
