# Symmetric Equation

MVCALC-OWHYYV

What is the symmetric equation of the line passing through the point $P=(2,-3,0)$ that is parallel to the vector ${\bf v}=\langle 3,-1,-4 \rangle$?

A

This line has no symmetric equation because one of the coordinates of $P$ is $0$.

B

$\cfrac{x-2}{3} =\cfrac{y+3}{-1} =\cfrac{z}{-4}$

C

$x=2+3t,\quad y=-3-t,\quad z=-4t$

D

$3(x-2)-(y+3)-4z=0$

E

$\cfrac{x-3}{2} =\cfrac{y+1}{-3} =\cfrac{z}{-4}$
