Hi there!

Looking at the graph, we can see exactly where the line crosses the y-axis (vertical line). The y-intercept is where the line goes through one point on the y-axis. The purple line goes perfectly through the point (0,4). Since the line goes through this point and the point is on the y-axis, the point (0,4), is the y-intercept. 

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
