Find a Set of Parametric Equations of the Line (7,4,7)( - 7,4,7 )

Question 159

Multiple Choice

Find a set of parametric equations of the line.
Passes through (7,4,7) ( - 7,4,7 ) and is perpendicular to x+4y+z=5- x + 4 y + z = 5 .


A) x=77ty=44tz=7+t\begin{array} { l } x = - 7 - 7 t \\y = 4 - 4 t \\z = 7 + t\end{array}
B) x=77ty=44tz=7t\begin{array} { l } x = - 7 - 7 t \\y = 4 - 4 t \\z = 7 - t\end{array}
C) x=77ty=4+4tz=7t\begin{array} { l } x = - 7 - 7 t \\y = 4 + 4 t \\z = 7 - t\end{array}
D) x=77ty=4+4tz=7+t\begin{array} { l } x = - 7 - 7 t \\y = 4 + 4 t \\z = 7 + t\end{array}
E) x=7+7ty=4+4tz=7+t\begin{array} { l } x = - 7 + 7 t \\y = 4 + 4 t \\z = 7 + t\end{array}
