यदि (y=mx+c) में (m+c=21) और (c=8), तो ढाल क्या है?
If (m+c=21) and (c=8) in (y=mx+c), what is the slope?
Explanation opens after your attempt
C. (13)
Concept
Putting (c=8) gives (m+8=21). Therefore (m=13).
Why this answer is correct
The correct answer is C. (13). Putting (c=8) gives (m+8=21). Therefore (m=13).
Exam Tip
(c=8) रखने पर (m+8=21) मिलता है। इसलिए (m=13) है।
