Find a vector-valued function, using the given parameter, to represent the intersection of the surfaces given below. $\begin{array}{ll}\text { Surfaces } & \text { Parameter } \\z=\frac{x^{2}}{25}+\frac{y^{2}}{64}, y+8 x=0 & x=t\end{array}$

A) $\mathbf { r } ( t ) = t \mathbf { i } - 8 t \mathbf { j } + \frac { 25 } { 26 } t ^ { 2 } \mathbf { k }$
B) $\mathbf { r } ( t ) = t \mathbf { i } + \frac { 26 } { 25 } t ^ { 2 } \mathbf { j } - 8 t \mathbf { k }$
C) $\mathbf { r } ( t ) = t \mathbf { i } + 8 t \mathbf { j } + \frac { 26 } { 25 } t ^ { 2 } \mathbf { k }$
D) $\mathbf { r } ( t ) = t \mathbf { i } + \frac { 25 } { 26 } t ^ { 2 } \mathbf { j } - 8 t \mathbf { k }$
E) $\mathbf { r } ( t ) = t \mathbf { i } - 8 t \mathbf { j } + \frac { 26 } { 25 } t ^ { 2 } \mathbf { k }$
