What is the (y)-intercept of the equation (y-7=-3x)?समीकरण (y-7=-3x) का (y)-अवरोध क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(7\)\(7\)
Moving 7 to the right gives \(y=-3x+7\). To find the \(y\)-intercept, put \(x=0\); then \(y=7\). Hence, the \(y\)-intercept is \(7\). Here, \(-3\) is the slope, not the \(y\)-intercept. Exam tip: in \(y=mx+c\), \(c\) is the \(y\)-intercept.दिए गए समीकरण में 7 को दाईं ओर ले जाने पर \(y=-3x+7\) मिलता है। \(y\)-अवरोध ज्ञात करने के लिए \(x=0\) रखें; तब \(y=7\) होगा। इसलिए \(y\)-अवरोध \(7\) है। \(-3\) ढाल है, \(y\)-अवरोध नहीं। परीक्षा टिप: \(y=mx+c\) में \(c\), \(y\)-अवरोध होता है।
