To use the method of substitution, we need to solve one of the equations for one of the variables. Let's use the first equation: 
$$y = x^2 - 6$$ 
We can substitute this expression for y into the second equation: 
$$\sqrt{36-x^2} = -y$$ 
We know that the square root of 36 is 6, so we can simplify this equation as: 
$$6 = -y$$ 
Dividing both sides by -1, we get: 
$$-6 = y$$ 
Therefore, the y-coordinate of the solution is -6. The answer is B.
