To find the initial value (b) of the linear function in the form \(y = mx + b\), we can use the rate of change \(m = -\frac{4}{7}\) and the point \((14, 3)\) given.

We can substitute \(m\), \(x\), and \(y\) into the equation to solve for \(b\):

  1. Start with the equation:
    \[ y = mx + b \]

  2. Substitute the values:
    \[ 3 = -\frac{4}{7} \cdot 14 + b \]

  3. Now, calculate \(-\frac{4}{7} \cdot 14\):
    \[ -\frac{4}{7} \cdot 14 = -\frac{56}{7} = -8 \]

  4. Substitute back into the equation:
    \[ 3 = -8 + b \]

  5. Solve for \(b\):
    \[ b = 3 + 8 = 11 \]

The initial value \(b\) of the linear function is 11.

So the correct answer is: B = 11.
