The given function is \( g(x) = 15 - 8x \), and you are asked to find the value of \( g(-6) \).

We can do this by substituting \( x = -6 \) into the function:

\[
g(-6) = 15 - 8(-6)
\]

Now, calculate the result:

\[
g(-6) = 15 + 48 = 63
\]

So, the value of \( g(-6) \) is **63**, which corresponds to option **D**.

2. What is the slope of the function \( g(x) = 15 - 8x \)?
3. If \( g(x) = 0 \), what is the value of \( x \)?
4. How would you graph \( g(x) = 15 - 8x \)?
5. Can you find the inverse of the function \( g(x) = 15 - 8x \)?

**Tip**: When dealing with linear functions like this, substituting values into the formula is straightforward, but always watch for negative signs!
