Line through two given points: symmetric form for JEE

Formula

\(\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1}=\frac{z-z_1}{z_2-z_1}\)

Variables: Line through \(P(x_1,y_1,z_1)\) and \(Q(x_2,y_2,z_2)\).

Conditions: Use modified form if any denominator is zero.

Direct line equation from two points.
