To find the initial value (y-intercept) \( b \) of the linear function given the slope \( m \) and a point \( (x, y) \), you can use the point-slope form of a linear equation:

\[ y = mx + b \]

In this case, you have:

  • \( m = -\frac{47}{1} \) (which simplifies to just \(-47\))
  • The point \( (14, 3) \)

Substituting the point into the equation:

\[ 3 = -47(14) + b \]

Now calculate \( -47(14) \):

\[ -47 \times 14 = -658 \]

Now substitute this back into the equation:

\[ 3 = -658 + b \]

To solve for \( b \), add \( 658 \) to both sides:

\[ b = 3 + 658 \] \[ b = 661 \]

Now, let's reevaluate if any of the provided choices match \( b = 661 \). None of the provided options (15.71, 12.29, -5, 11) are correct.

Therefore, if you follow the typical expectations of linear equations, based on the calculations, the initial value (y-intercept) \( b \) of the linear function is actually 661. None of the provided answer options are correct or close to the computed value.
