Consider the line with these parametric equations:

$x=-5t+8$

$y=2t-2$

$z=6t+8$

One set of symmetric equations for this line is

$\frac{x-8}{-5}=\frac{y-y_0}{b}=\frac{z-z_0}{c}$

where $y_0=,z_0=,b=,$ and $c=$

Another set of symmetric equations for this line is

$\frac{x}{5}=\frac{y-y_1}{b}=\frac{z-z_1}{c}$

where $y_1=z_1=,b=,$ and $c=$
