<reasoning>

Identify the slopes of the first pair of lines

\[

$$\begin{aligned} &y_1 = 8x + 2 \implies m_1 = 8 \\ &y_2 = 8x + 3 \implies m_2 = 8 \end{aligned}$$

\]

Identify the slopes of the second pair of lines

\[

$$\begin{aligned} &y_3 = 3x - 2 \implies m_3 = 3 \\ &y_4 = 4x + 2 \implies m_4 = 4 \end{aligned}$$

\]

Compare slopes to determine parallel lines

\[

$$\begin{aligned} &m_1 = m_2 = 8 \implies \text{Parallel} \\ &m_3 e m_4 \implies \text{Not Parallel} \end{aligned}$$

\]
