$\begin{array}{l}
e)\Delta //d\\
\Rightarrow \Delta :2x - 3y + c = 0\left( {c \ne - 3} \right)\\
Do:G\left( { - 2;5} \right) \in \Delta \\
\Rightarrow 2.\left( { - 2} \right) - 3.5 + c = 0\\
\Rightarrow c = 19\left( {tm} \right)\\
\Rightarrow \Delta :2x - 3y + 19 = 0\\
f)\Delta \bot d\\
\Rightarrow \Delta :3x + 2y + d = 0\\
\Rightarrow 3.\left( { - 2} \right) + 2.5 + d = 0\\
\Rightarrow d = - 4\\
\Rightarrow \Delta :3x + 2y - 4 = 0
\end{array}$
