1. **State the problem:** Solve the system of inequalities by graphing:
$$y < -2$$
$$y > 10x - 9$$
2. **Understand the inequalities:**
- The first inequality, $$y < -2$$, represents all points below the horizontal line $$y = -2$$.
- The second inequality, $$y > 10x - 9$$, represents all points above the line $$y = 10x - 9$$.
3. **Graph the boundary lines:**
- For $$y = -2$$, this is a horizontal line crossing the y-axis at -2.
- For $$y = 10x - 9$$, this is a line with slope 10 and y-intercept -9.
4. **Determine line types:**
- Both inequalities are strict ("<" and ">"), so both boundary lines are dotted (not solid).
5. **Shade the solution region:**
- Shade below the line $$y = -2$$.
- Shade above the line $$y = 10x - 9$$.
6. **Find the intersection region:**
- The solution is the region where these shaded areas overlap.
7. **Check intersection points:**
- Find where $$y = -2$$ intersects $$y = 10x - 9$$:
$$-2 = 10x - 9$$
$$-2 + 9 = 10x$$
$$7 = 10x$$
$$x = \frac{7}{10}$$
- So the lines intersect at $$\left(\frac{7}{10}, -2\right)$$.
8. **Summary:**
- The solution is all points $$\left(x,y\right)$$ such that $$y < -2$$ and $$y > 10x - 9$$.
- Graphically, this is the region below the dotted horizontal line $$y = -2$$ and above the dotted line $$y = 10x - 9$$, between and beyond their intersection at $$\left(\frac{7}{10}, -2\right)$$.
**Final answer:** The solution region is the area below $$y = -2$$ and above $$y = 10x - 9$$ with both boundary lines dotted.
