Question: Given the system of inequalities and the corresponding graph below, which section of the graph represents all of the solutions to the system?
y \geq 7x
y \geq -2x - 2
x-axis horizontal through y = 0; y-axis vertical through x = 0; graph split into four labeled regions: Section A at the top, Section B on the right, Section C at the bottom, and Section D on the left; the overlapping solution region for the inequalities is Section A, near the top-center. position_hint: center
(A) Section A
1. **State the problem:** We need to find which section of the graph represents all solutions to the system of inequalities:
$$y \geq 7x$$
$$y \geq -2x - 2$$
2. **Understand the inequalities:**
- The first inequality, $$y \geq 7x$$, represents the region above or on the line $$y = 7x$$.
- The second inequality, $$y \geq -2x - 2$$, represents the region above or on the line $$y = -2x - 2$$.
3. **Find the intersection of the two regions:**
- The solution to the system is the intersection of the two half-planes defined by the inequalities.
- This means the solution region is where both $$y \geq 7x$$ and $$y \geq -2x - 2$$ hold true simultaneously.
4. **Analyze the graph sections:**
- Section A is at the top-center, above both lines.
- Section B is on the right side.
- Section C is at the bottom.
- Section D is on the left.
5. **Conclusion:**
- Since the solution region is above both lines, it corresponds to Section A.
**Final answer:** Section A
