1. **State the problem:** Find all x-intercepts of the function $$f(x) = \frac{x + 8}{5x + 8}$$ and write them as coordinate points.
2. **Recall the formula for x-intercepts:** The x-intercepts occur where the function value is zero, i.e., where $$f(x) = 0$$.
3. **Set the numerator equal to zero:** Since $$f(x) = \frac{\text{numerator}}{\text{denominator}}$$, the function is zero when the numerator is zero (and denominator is not zero).
$$x + 8 = 0$$
4. **Solve for x:**
$$x = -8$$
5. **Check denominator at x = -8:**
$$5(-8) + 8 = -40 + 8 = -32 \neq 0$$
So the function is defined at $$x = -8$$.
6. **Write the x-intercept as a coordinate point:**
$$(-8, 0)$$
**Final answer:** The function has one x-intercept at $$(-8, 0)$$.
