यदि (y=mx+c) में (m=-5) और (3c+m=31), तो (y)-अवरोध क्या है?
If (m=-5) and (3c+m=31) in (y=mx+c), what is the (y)-intercept?
Explanation opens after your attempt
C. (12)
Concept
Putting (m=-5) gives (3c-5=31). Thus (3c=36) and (c=12).
Why this answer is correct
The correct answer is C. (12). Putting (m=-5) gives (3c-5=31). Thus (3c=36) and (c=12).
Exam Tip
(m=-5) रखने पर (3c-5=31) मिलता है। इससे (3c=36) और (c=12) है।
