1. **State the problem:** Find the slope and y-intercept of the line given by the equation $y = 3x - 1$. 2. **Recall the slope-intercept form:** The equation of a line in slope-intercept form is $$y = mx + b$$ where $m$ is the slope and $b$ is the y-intercept. 3. **Identify slope and y-intercept:** In $y = 3x - 1$, the slope $m = 3$ and the y-intercept $b = -1$. 4. **Interpretation:** The slope $3$ means the line rises 3 units vertically for every 1 unit it moves horizontally. 5. **Final answer:** Slope = 3, y-intercept = -1. This matches the given answers for problem 1: slope letter is L (3), y-intercept letter is A (-1).
