यदि (y=mx+c) में (c=-12) और (m-c=21), तो ढाल क्या है?
If (c=-12) and (m-c=21) in (y=mx+c), what is the slope?
Explanation opens after your attempt
C. (9)
Concept
Putting (c=-12) gives (m-(-12)=21). So (m+12=21) and (m=9).
Why this answer is correct
The correct answer is C. (9). Putting (c=-12) gives (m-(-12)=21). So (m+12=21) and (m=9).
Exam Tip
(c=-12) रखने पर (m-(-12)=21) मिलता है। इसलिए (m+12=21) और (m=9) है।
