यदि (y=(k-7)x+6) और (y=4x+(k-1)) की ढालें समान हैं, तो (k) क्या है?
If (y=(k-7)x+6) and (y=4x+(k-1)) have equal slopes, what is (k)?
Explanation opens after your attempt
C. (11)
Concept
For equal slopes, (k-7=4). This gives (k=11).
Why this answer is correct
The correct answer is C. (11). For equal slopes, (k-7=4). This gives (k=11).
Exam Tip
समान ढाल के लिए (k-7=4) होगा। इससे (k=11) मिलता है।
