$y=-\frac{3}{5}(x+4)$

Recall: The equation of a line whose slope is $m$ and passes through the point $(x_1, y_1)$ is: $$y-y_1=m(x-x_1)$$ Thus, the equation of the line whose slope is $-\dfrac{3}{5}$ and passes through the point $(-4, 0)$ is: \begin{align*} y-0&=-\frac{3}{5}\left[x-(-4)\right]\\ y&=-\frac{3}{5}(x+4) \end{align*}
