If (m+c=21) and (c=8) in (y=mx+c), what is the slope?यदि (y=mx+c) में (m+c=21) और (c=8), तो ढाल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1313
In the equation of a line, the slope is represented by \(m\). Given \(m+c=21\) and \(c=8\), we get \(m+8=21\). Hence, \(m=21-8=13\). Therefore, the correct answer is 13. Note that 8 is \(c\), the y-intercept, not the slope. Exam tip: in \(y=mx+c\), the coefficient \(m\) is always the slope.रेखा के समीकरण में ढाल को \(m\) से दर्शाया जाता है। दिया है \(m+c=21\) तथा \(c=8\)। अतः \(m+8=21\), इसलिए \(m=21-8=13\)। इसलिए सही उत्तर 13 है। 8, \(c\) अर्थात y-अवरोध है, ढाल नहीं। परीक्षा टिप: \(y=mx+c\) में ढाल हमेशा \(m\) होती है।
