यदि (p(x)=ax+b) रेखीय है, तो (a) के बारे में सही बात कौन सी है?
If (p(x)=ax+b) is linear, which statement about (a) is correct?
Explanation opens after your attempt
B. (a) शून्य नहीं हो(a) is not zero
Concept
For being linear, the coefficient (a) of (x) must not be zero. Then the degree remains (1).
Why this answer is correct
The correct answer is B. (a) शून्य नहीं हो / (a) is not zero. For being linear, the coefficient (a) of (x) must not be zero. Then the degree remains (1).
Exam Tip
रेखीय होने के लिए (x) का गुणांक (a) शून्य नहीं होना चाहिए। तभी डिग्री (1) रहती है।
