General line coefficients and slope relation for JEE
The slope of a line, parallel and perpendicular lines
Formula
\(ax+by+c=0\Rightarrow m=-\dfrac{a}{b}\)
Variables: \(a,b,c\) are constants.
Conditions: \(b\ne 0\). If \(b=0\), line is vertical.
Converting line equations, angle and parallel/perpendicular conditions.
