यदि (y=(m+2)x-8) और (y=9x+(m-12)) का (y)-अवरोध समान है, तो (m) क्या है?
If (y=(m+2)x-8) and (y=9x+(m-12)) have the same (y)-intercept, what is (m)?
Explanation opens after your attempt
D. (4)
Concept
For equal (y)-intercepts, (-8=m-12). This gives (m=4).
Why this answer is correct
The correct answer is D. (4). For equal (y)-intercepts, (-8=m-12). This gives (m=4).
Exam Tip
समान (y)-अवरोध के लिए (-8=m-12) होगा। इससे (m=4) मिलता है।
