Question

The cartesian equation of a line through $(x_1,y_1,z_1)$ with direction ratios $a,b,c$ is:

Accepted Answer

C. $	frac{x-x_1}{a}=	frac{y-y_1}{b}=	frac{z-z_1}{c}$

The symmetric (cartesian) form of a line is (x−x₁)/a = (y−y₁)/b = (z−z₁)/c.

Answer

$	frac{x-x_1}{a}+	frac{y-y_1}{b}+	frac{z-z_1}{c}=1$

Answer

$	frac{a}{x-x_1}=	frac{b}{y-y_1}=	frac{c}{z-z_1}$

Answer

$ax+by+cz=0$
