यदि (y=mx+c) में (c=-18) और (m-c=31), तो ढाल क्या है?
If (c=-18) and (m-c=31) in (y=mx+c), what is the slope?
Explanation opens after your attempt
C. (13)
Concept
Putting (c=-18) gives (m-(-18)=31). Therefore (m=13).
Why this answer is correct
The correct answer is C. (13). Putting (c=-18) gives (m-(-18)=31). Therefore (m=13).
Exam Tip
(c=-18) रखने पर (m-(-18)=31) मिलता है। इसलिए (m=13) है।
