1. **State the problem:** We are given two equations:
$$y = -3x^2 + 2x - 5$$
and
$$-x + 2 = -y$$
We want to analyze these equations, find their points of intersection, and understand their graphs.
2. **Rewrite the linear equation:** From $$-x + 2 = -y$$, multiply both sides by $$-1$$ to isolate $$y$$:
$$-x + 2 = -y$$
$$\Rightarrow y = x - 2$$
3. **Set the two expressions for $$y$$ equal to find intersection points:**
$$-3x^2 + 2x - 5 = x - 2$$
4. **Bring all terms to one side:**
$$-3x^2 + 2x - 5 - x + 2 = 0$$
$$-3x^2 + (2x - x) + (-5 + 2) = 0$$
$$-3x^2 + x - 3 = 0$$
5. **Solve the quadratic equation:**
$$-3x^2 + x - 3 = 0$$
Multiply both sides by $$-1$$ to simplify:
$$\cancel{-3}x^2 + \cancel{-1}x + \cancel{-3} = 0 \Rightarrow 3x^2 - x + 3 = 0$$
6. **Calculate the discriminant $$\Delta$$:**
$$\Delta = b^2 - 4ac = (-1)^2 - 4 \times 3 \times 3 = 1 - 36 = -35$$
7. **Interpret the discriminant:** Since $$\Delta < 0$$, there are no real solutions, meaning the parabola and the line do not intersect.
8. **Summary:** The quadratic curve $$y = -3x^2 + 2x - 5$$ opens downward, and the line $$y = x - 2$$ does not intersect it because the quadratic equation formed by setting them equal has no real roots.
**Final answer:** No real intersection points exist between the two given equations.
