\\(y = -\frac{3}{4}x + 8\\)
\\(y = -\frac{3}{4}x + 6\\)
\\(y = \frac{4}{3}x - 8\\)
\\(y = \frac{4}{3}x - 6\\)

Find the slope of the given line

\[

$$\begin{aligned} (x_1, y_1) &= (-4, 4) \\ (x_2, y_2) &= (4, -2) \\ m_{\text{given}} &= \frac{-2 - 4}{4 - (-4)} = \frac{-6}{8} = -\frac{3}{4} \end{aligned}$$

\]

Determine the perpendicular slope

\[

$$\begin{aligned} m_{\perp} &= -\frac{1}{m_{\text{given}}} \\ m_{\perp} &= \frac{4}{3} \end{aligned}$$

\]

Find the equation with x-intercept of 6

\[

$$\begin{aligned} (x, y) &= (6, 0) \\ y - y_1 &= m_{\perp}(x - x_1) \\ y - 0 &= \frac{4}{3}(x - 6) \\ y &= \frac{4}{3}x - 8 \end{aligned}$$
