Correct Answer

B. (9)

Step 1

Concept

To pass through the origin, (r-3=0). Thus (r=3) and the slope is (r+6=9).

Step 2

Why this answer is correct

The correct answer is B. (9). To pass through the origin, (r-3=0). Thus (r=3) and the slope is (r+6=9).

Step 3

Exam Tip

मूल बिंदु से गुजरने के लिए (r-3=0) होगा। इसलिए (r=3) और ढाल (r+6=9) है।
