यदि (y=(a+9)x+(a-15)) मूल बिंदु से गुजरती है, तो इसकी ढाल क्या होगी?
If (y=(a+9)x+(a-15)) passes through the origin, what will be its slope?
Explanation opens after your attempt
C. (24)
Concept
To pass through the origin, (a-15=0). Thus (a=15) and the slope is (24).
Why this answer is correct
The correct answer is C. (24). To pass through the origin, (a-15=0). Thus (a=15) and the slope is (24).
Exam Tip
मूल बिंदु से गुजरने के लिए (a-15=0) होगा। इसलिए (a=15) और ढाल (24) है।
