Answer
Slope: $-2$
Y-Intercept: $-5$
See image for graph.
Work Step by Step
The $\text{slope-intercept}$ form of a linear equation is $y=mx+b$, where $m$ is the $\text{slope}$ and $b$ is the $y$-$\text{intercept}$. The given equation is $y=-2x-5$. Since $-2$ takes the place of the $m$, it is the $\text{slope}$. Since $-5$ takes the place of $b$, it is the $y$-$\text{intercept}$. To graph this line, we make sure that it crosses the $y$-axis at $y=-5$ and that the line goes down $2$ every time it goes 1 to the right.
