# Math Help - Equation of plan

1. ## Equation of plan

Finding the equation of the plan that passes the straight r: $\frac{(x-1)}{3}=\frac{(y-3)}{2}=\frac{(z+2)}{-1}$ and is parallel to the straight s:
x-y+z-3=0
x+y-z+5=0

answer:
x-y+z+4=0

2. How do I find the vector of directional
straight (s)?
