Here's the graph of the line $y = x - 1$, which includes the line itself and a red dot at the y-intercept $(0, -1)$. Would you like further details on how the slope and y-intercept were applied here?

1. How can we identify the slope from a linear equation?
2. What is the significance of the y-intercept in a graph?
3. How would the line change if we altered the slope?
4. What happens if we change the y-intercept in this equation?
5. Can we graph this line using another method?

Tip: For any line in the form $y = mx + b$, $m$ represents the slope, and $b$ is the y-intercept.
