To derive the equation of a line in slope-intercept form (y = mx + b), you need to identify the slope (m) and the y-intercept (b) from the graph.

1. **Identifying the slope (m)**: The slope is the rise over run. If the line goes up 3 units for every 1 unit it moves to the right, then the slope is 3.

2. **Identifying the y-intercept (b)**: This is the point where the line crosses the y-axis. If the line crosses the y-axis at -4, then the y-intercept is -4.

Combining these, the slope-intercept form of the line is:

\[
y = 3x - 4
\]

Based on the options provided, the correct response is:

**y = 3x - 4**
