Find Numbers a and B, or K, So That F $f ( x ) = \left\{ \begin{array} { l l } 10 x + 8 , & \text { if } x < - 7 \\ k x + 2 , & \text { if } x \geq - 7 \end{array} \right.$

Multiple Choice

- $f ( x ) = \left\{ \begin{array} { l l } 10 x + 8 , & \text { if } x < - 7 \\ k x + 2 , & \text { if } x \geq - 7 \end{array} \right.$

A) $\mathrm { k } = \frac { 64 } { 7 }$
B) $\mathrm { k } = \frac { 2 } { 7 }$
C) $k = 16$
D) $k = - \frac { 2 } { 7 }$
