यदि (ay=42x-70) की ढाल (7) है, तो (a) का मान क्या है?
If (ay=42x-70) has slope (7), what is the value of (a)?
Explanation opens after your attempt
B. (6)
Concept
\(y=\frac{42}{a}x-\frac{70}{a}\). From \(\frac{42}{a}=7\), (a=6).
Why this answer is correct
The correct answer is B. (6). \(y=\frac{42}{a}x-\frac{70}{a}\). From \(\frac{42}{a}=7\), (a=6).
Exam Tip
\(y=\frac{42}{a}x-\frac{70}{a}\) होगा। \(\frac{42}{a}=7\) से (a=6) है।
