To determine the value of the y-coordinate where the line crosses the y-axis, we need to understand that the point where a line crosses the y-axis has the form $(0, y)$, where $x = 0$.

However, you haven't provided the equation of the line. If you could provide that information, I can calculate the exact value of $y$ when $x = 0$ and give you the correct answer.

Could you share the equation of the line?

If you'd like, here are some follow-up questions:

1. How do you determine the slope of a line from its equation?
2. What is the general form of a linear equation?
3. How do you find the x-intercept of a line?
4. What is the significance of the y-intercept in real-world problems?
5. How can you graph a linear equation using its slope and y-intercept?

Tip: When you graph a linear equation, always start by plotting the y-intercept, then use the slope to find other points!
