In the equation of a line \(y=mx+c\), which property is determined by the sign of \(m\)?

Answer and explanation

Correct answer: रेखा बाएँ से दाएँ ऊपर जाती है या नीचे

\(m\) is the slope. If \(m>0\), the line rises from left to right; if \(m<0\), it falls. The y-intercept is determined by \(c\), not by the sign of \(m\). Exam tip: inspect the sign of \(m\) first.
