thats a goood question let me seee
Step-by-step explanation:
The Y-intercept is -4 because it's located on the y-axis you can remember that the y-axis is up and down the x-axis is side to side.
or 
At the point/angle E:
- the adjacent side(side <u>next to</u> the point/angle) is ED
- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF
- the hypotenuse (the<u> longest side</u> of the triangle) is EF.
sin ∠E = 
sin ∠E =
(simplified)
I would say B but I can't see the question very well.
