If you know the derivative
of some function
, you can tell exactly who
is, up to an additive, constant term. In fact, knowing
, you have

In your case, we have

So, the integral is almost immediate:

So, up to some constant additive term, our function is 
To fix this constant, we know that the function passes through the point (6,10), so we have

And so our function is 
If we want to know when this function equals 6, we simply have to ask
and solve for x, so we have

Answer:
1890 yd

[ Answer ]

[ Explanation ]
Y = X + 2 is saying that Y, is the X dot + 2.
When the X dot is on 0, we have to add 2 to get to where the Y dot is. X (0) + 2 = 2. That is where the Y dot is.
X (2) + 2 = 4. 4 is where the Y dot is,
Once you keep adding the X dots to 2, you will get the Y dots. That is why the equation is Y = X + 2. In order to get to Y, you need to add 2 to the X dot.
