See the entire solution process below:

#### Explanation:

To find $g \left(- 2\right)$ substitute $\textcolor{red}{- 2}$ for each occurrence of $\textcolor{red}{x}$ in $g \left(x\right)$:

$g \left(\textcolor{red}{x}\right) = - 5 \textcolor{red}{x} + 2$ becomes:

$g \left(\textcolor{red}{- 2}\right) = \left(- 5 \times \textcolor{red}{- 2}\right) + 2$

$g \left(\textcolor{red}{- 2}\right) = 10 + 2$

$g \left(\textcolor{red}{- 2}\right) = 12$
