Equation in slope intercept that is parallel to 3+4x=2y-9 and goes through (4,-4)

If it's parallel to that equation, then that means the slope must be the same
Using the equation they gave us, we find the slope: 
3+4x=2y-9
12+4x=2y
y=2x+6 (I just rearranged it after dividing both sides by 2)
Therefore, the slope of the equation is 2
So y=2x+b
Then they gave us the point (4,-4) and we can use that to find the intercept by plugging the values in for x and y:
-4=2(4)+b
-4=8+b
b=-12

So the equation is y=2x-12

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy
