1. **State the problem:** Solve the system of equations by graphing:
$$y = -x^2 + 4x + 2$$
$$y = x - 2$$
Find the points where the parabola and the line intersect.
2. **Set the equations equal to find intersection points:**
Since both equal $y$, set:
$$-x^2 + 4x + 2 = x - 2$$
3. **Bring all terms to one side:**
$$-x^2 + 4x + 2 - x + 2 = 0$$
Simplify:
$$-x^2 + 3x + 4 = 0$$
4. **Multiply both sides by $-1$ to simplify:**
$$\cancel{-}1 \times (-x^2 + 3x + 4) = \cancel{-}1 \times 0$$
$$x^2 - 3x - 4 = 0$$
5. **Factor the quadratic:**
$$x^2 - 3x - 4 = (x - 4)(x + 1) = 0$$
6. **Solve for $x$:**
$$x - 4 = 0 \Rightarrow x = 4$$
$$x + 1 = 0 \Rightarrow x = -1$$
7. **Find corresponding $y$ values using $y = x - 2$:**
For $x=4$:
$$y = 4 - 2 = 2$$
For $x=-1$:
$$y = -1 - 2 = -3$$
8. **Write the solutions as ordered pairs:**
$$(-1, -3) \quad \text{and} \quad (4, 2)$$
**Final answer:** The solutions to the system are $(-1, -3)$ and $(4, 2)$.
