For the line \(ax+by+c=0\), where \(b\ne0\), which expression represents the \(y\)-intercept?रेखा \(ax+by+c=0\) में, जहाँ \(b\ne0\), \(y\)-अवरोध की पहचान कौन-सी है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(-\frac{c}{b}\)\(-\frac{c}{b}\)
To find the \(y\)-intercept, put \(x=0\). Then \(by+c=0\), so \(y=-\frac{c}{b}\). The expression \(-\frac{a}{b}\) gives the slope, not the intercept. Exam tip: set \(x=0\) first.\(y\)-अवरोध के लिए \(x=0\) रखते हैं। तब \(by+c=0\), इसलिए \(y=-\frac{c}{b}\) मिलता है। \(-\frac{a}{b}\) रेखा की ढाल है, अवरोध नहीं। परीक्षा में पहले \(x=0\) रखें।
