Encontre as equações paramétricas da reta r que passa pelo ponto (1,3,7)(-1,-3,7) e é paralela à reta s:x13=y+31=z74s: \frac{x-1}{3}=\frac{y+3}{-1}=\frac{z-7}{4}. a) r:x13=y+31=z74r: \frac{x-1}{3}=\frac{y+3}{-1}=\frac{z-7}{4}. b) {x=1+3ty=3tz=7+4ttR\left\{\begin{array}{l}x=-1+3 t \\ y=-3-t \\ z=7+4 t\end{array} \quad t \in \mathbb{R}\right.. c) (x+1,y+3,z7)=t(3,1,4)tR(x+1, y+3, z-7)=t(3,-1,4) \quad t \in R. d) {x=1+3ty=3tz=7+4ttR\left\{\begin{array}{l}x=-1+3 t \\ y=-3-t \\ z=-7+4 t\end{array} \quad t \in \mathbb{R}\right.. e) {x=13ty=3tz=74t\left\{\begin{array}{l}x=-1-3 t \\ y=-3-t \\ z=7-4 t\end{array}\right.
