Which of the following equations represents a line that has no y-intercept?निम्नलिखित में से किस समीकरण द्वारा निरूपित रेखा का y-अवरोध नहीं होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(x=5\)\(x=5\)
\(x=5\) is a vertical line and never meets the y-axis, whose equation is \(x=0\); hence it has no y-intercept. In contrast, \(y=2x+1\) meets it at 1. Exam tip: \(x=c\), for \(c\ne0\), has no y-intercept.\(x=5\) एक ऊर्ध्वाधर रेखा है, जो y-अक्ष \((x=0)\) को नहीं काटती; इसलिए इसका y-अवरोध नहीं है। \(y=2x+1\) में y-अवरोध 1 है। परीक्षा टिप: \(x=c\), जहाँ \(c\ne0\), का y-अवरोध नहीं होता।
