We will use the Sine Law:

b = 5.001
Answer:
D) 5.0
The answer is nonlinear. It goes in a sharp downward curve, whereas a linear function is a straight line.
Follow these steps:
-8.4b - 4.2 = 12.6
Add 4.2 on both sides:
-8.4b = 16.8
Divide by -8.4 on both sides to give you the final answer of:
b = -2
So you're answer is indeed correct! Hope this helps and that the steps are clear enough!
