Answer
The slope is $-1$ and the y-intercept is $10$.
Work Step by Step
This equation is already written in slope-intercept form, so we can easily see what the slope and y-intercept are for this line.
The slope-intercept form is given by:
$$y = mx + b$$
where $m$ is the slope and $b$ is the y-intercept.
We see that $m = -1$ and $b$, the y-intercept, is $10$.
