The y-intercept of a line is the point where the line crosses the y-axis (vertical axis). From the given graph, the line crosses the y-axis at the point $(0, -2)$.

Therefore, the y-intercept is:

D. -2

Would you like a detailed explanation or have any questions? Here are 5 related questions to further explore:

1. How do you find the x-intercept of a line from a graph?
2. What is the slope of the line shown in the graph?
3. How would the graph change if the y-intercept was positive?
4. Can you explain how to determine the equation of this line?
5. What does the y-intercept represent in the context of a real-world problem?

Tip: The y-intercept can be easily identified by setting $x = 0$ in the equation of the line and solving for $y$.
