If (y=3x+c) has (y)-intercept (2), what will (y) be at (x=4)?यदि (y=3x+c) का (y)-अवरोध (2) है तो (x=4) पर (y) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1414
The y-intercept is 2, so the constant in the equation is \(c=2\). Substituting \(x=4\), we get \(y=3\times4+2=14\). Therefore, 14 is correct. The value 12 is only \(3\times4\); the y-intercept 2 must also be added. Exam tip: in \(y=mx+c\), the y-intercept is always \(c\).रेखा का y-अवरोध 2 है, इसलिए समीकरण में स्थिरांक \,\(c=2\) होगा। अतः \(x=4\) रखने पर \(y=3\times4+2=14\)। इसलिए सही उत्तर 14 है। 12 केवल \(3\times4\) है; इसमें y-अवरोध 2 जोड़ना आवश्यक है। परीक्षा टिप: \(y=mx+c\) में y-अवरोध हमेशा \(c\) होता है।
