यदि (y=mx+c) में (m=-4) और (2c+m=18), तो (y)-अवरोध क्या है?
If (m=-4) and (2c+m=18) in (y=mx+c), what is the (y)-intercept?
Explanation opens after your attempt
C. (11)
Concept
Putting (m=-4) gives (2c-4=18). Thus (2c=22) and (c=11).
Why this answer is correct
The correct answer is C. (11). Putting (m=-4) gives (2c-4=18). Thus (2c=22) and (c=11).
Exam Tip
(m=-4) रखने पर (2c-4=18) मिलता है। इससे (2c=22) और (c=11) है।
