Find the slope and the y-intercept of the graph of the linear equation.

y = -1

The equation given is:

\[
y = -1
\]

This is a horizontal line where \( y \) is always \(-1\), regardless of the value of \( x \).

### Slope
For a horizontal line, the slope is always \( 0 \) because there is no change in \( y \) as \( x \) changes. Mathematically, slope \( m = 0 \).

### Y-Intercept
The y-intercept is the point where the line crosses the y-axis. Here, since \( y = -1 \) at all points, the y-intercept occurs at \( (0, -1) \).

**Summary:**
- **Slope**: \( m = 0 \)
- **Y-Intercept**: \( (0, -1) \)
