Determine the slope of the parallel line

\[

$$\begin{aligned} &y = -5x - 2 \implies m_1 = -5 \\ &m_2 = m_1 = -5 \end{aligned}$$

\]

Use point-slope form with the given point

\[

$$\begin{aligned} &(x_1, y_1) = (-3, -4) \\ &y - y_1 = m(x - x_1) \\ &y - (-4) = -5(x - (-3)) \\ &y + 4 = -5(x + 3) \end{aligned}$$

\]

Convert to slope-intercept form

\[

$$\begin{aligned} &y + 4 = -5x - 15 \\ &y = -5x - 19 \end{aligned}$$

\]
