यदि (y=mx+c) में ढाल (-7) है और (m+c=5), तो (y)-अवरोध क्या है?
If the slope is (-7) and (m+c=5) in (y=mx+c), what is the (y)-intercept?
Explanation opens after your attempt
C. (12)
Concept
Slope (-7) gives (m=-7). From (-7+c=5), (c=12).
Why this answer is correct
The correct answer is C. (12). Slope (-7) gives (m=-7). From (-7+c=5), (c=12).
Exam Tip
ढाल (-7) से (m=-7) है। (-7+c=5) से (c=12) है।
