## Calculus 8th Edition

Let $(x_0,y_0,_0)$ be a point on the line and $\lt a,b,c\gt$ be a direction vector of the line. Equation of the line is given by $r=r_0+tv$ Parametric equations are defined as: $x=x_0+at$, $y=y_0=bt$ and $z=z_0+ct$ The symmetric equations are defined as: $\frac{x-x_0}{a}=\frac{y-y_0}{b}=\frac{z-z_0}{c}$
