System Solutions 07A5B1
1. **State the problem:** We need to find which ordered pairs satisfy the system of inequalities represented by the two lines and their shading.
2. **Identify the lines and inequalities:**
- The first line is solid, descending, passing through points (0,2) and (-2,6). The slope $m$ is calculated as:
$$m=\frac{6-2}{-2-0}=\frac{4}{-2}=-2$$
The equation of the line using point-slope form with point (0,2) is:
$$y-2=-2(x-0)\implies y=-2x+2$$
Since the shading is on the upper left side, the inequality is:
$$y \geq -2x + 2$$
- The second line is dashed, vertical at $x=2$, shading is on the right side, so the inequality is:
$$x > 2$$
3. **Determine the solution region:** The solution region is where both inequalities hold:
$$\begin{cases} y \geq -2x + 2 \\ x > 2 \end{cases}$$
4. **Check each ordered pair:**
- (0,0): $x=0 \not> 2$ no
- (3,1): $x=3 > 2$ yes; check $y \geq -2(3)+2= -6+2=-4$; $1 \geq -4$ yes
- (-2,3): $x=-2 \not> 2$ no
- (-4,3): $x=-4 \not> 2$ no
- (4,-3): $x=4 > 2$ yes; check $y \geq -2(4)+2= -8+2=-6$; $-3 \geq -6$ yes
5. **Conclusion:** The ordered pairs that satisfy the system are (3,1) and (4,-3).
