In the line (y=0x+9), what change will occur in (y) when (x) increases by (12)?रेखा (y=0x+9) में (x) के (12) बढ़ने पर (y) में कितना परिवर्तन होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(0\)\(0\)
The equation is \(y=0x+9\), so its slope is \(0\). Therefore, when \(x\) increases by \(12\), the change in \(y\) is \(0\times 12=0\). Here, \(9\) is the y-intercept, not the change in \(y\). Exam tip: For \(y=mx+c\), use \(\Delta y=m\Delta x\).रेखा का समीकरण \(y=0x+9\) है, इसलिए इसकी ढाल \(0\) है। अतः \(x\) में \(12\) की वृद्धि करने पर \(y\) में परिवर्तन \(0\times 12=0\) होगा। \(9\) रेखा का y-अंतःखंड है, परिवर्तन नहीं। परीक्षा टिप: \(y=mx+c\) में \(x\) के परिवर्तन \(\Delta x\) के लिए \(\Delta y=m\Delta x\) लें।
