1. **Problem statement:** We are given two functions: a line $f(x)$ (graph shown) and a quadratic function $g(x) = -x^2 - 3x - 5$. We need to find the intersection points of their graphs.
2. **Identify the line equation:** From the description, the line crosses the y-axis at about $-2$ and the x-axis at about $2$. The slope $m$ is calculated as:
$$m = \frac{0 - (-2)}{2 - 0} = \frac{2}{2} = 1$$
So the line equation is:
$$f(x) = x - 2$$
3. **Set the functions equal to find intersections:**
$$f(x) = g(x)$$
$$x - 2 = -x^2 - 3x - 5$$
4. **Rearrange to form a quadratic equation:**
$$x - 2 + x^2 + 3x + 5 = 0$$
$$x^2 + 4x + 3 = 0$$
5. **Factor the quadratic:**
$$x^2 + 4x + 3 = (x + 1)(x + 3) = 0$$
6. **Solve for $x$:**
$$x + 1 = 0 \Rightarrow x = -1$$
$$x + 3 = 0 \Rightarrow x = -3$$
7. **Find corresponding $y$ values using $f(x)$:**
$$f(-1) = -1 - 2 = -3$$
$$f(-3) = -3 - 2 = -5$$
8. **Intersection points:**
$(-1, -3)$ and $(-3, -5)$
**Final answer:** The graphs intersect at points $(-1, -3)$ and $(-3, -5)$.
