यदि (y=(a-7)x+a) में ढाल और (y)-अवरोध का अंतर (-7) है, तो कौन सा कथन सही है?
If in (y=(a-7)x+a), the difference between slope and (y)-intercept is (-7), which statement is correct?
Explanation opens after your attempt

Concept
The slope is (a-7) and the (y)-intercept is (a). The difference ((a-7)-a=-7) holds for every (a).
