$y-5=-(x+3)$

#### Work Step by Step

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 $-1$ and passes through the point $(-3, 5)$ is: \begin{align*} y-5&=-1[x-(-3)]\\ y-5&=-(x+3) \end{align*}
