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 $10$.
