Find the parametric equations for the line through (1, -1, 1) and parallel to the line x+2=0.5y=z-3
How do I obtain the direction of the line? Thanks
Hello, c_323_h!
Find the parametric equations for the line through $\displaystyle (1,-1,1)$
and parallel to the line $\displaystyle x+2\;=\;\frac{1}{2}y\;=\;z-3$
How do I obtain the direction of the line?
They gave us the symmetric form of the line: .$\displaystyle \frac{x + 2}{1}\;=\;\frac{y}{2}\;=\;\frac{z-3}{1}$
The direction vector is: .$\displaystyle \langle1,\,2,\,1\rangle$ . . . the denominators.
