Slope in terms of inclination for JEE
The slope of a line, parallel and perpendicular lines
Formula
\(m=\tan\theta\)
Variables: \(\theta\) is inclination of the line with positive \(x\)-axis.
Conditions: For non-vertical line; \(\theta\ne \frac{\pi}{2}+k\pi\).
Angle interpretation, line orientation.
