\[
\left\{\begin{array}{l}
y \geq -x + 4 \\
y \leq 2x + 6
\end{array}\right.
\]
Solution
Solution Steps
Step 1: Find two points that satisfy the first inequality
For $y = -x + 4$,
If $x=0$, then $y=4$. Thus, the point is $(0,4)$.
If $y=0$, then $0 = -x+4$, or $x=4$. Thus, the point is $(4,0)$.
Step 2: Find two points that satisfy the second inequality
For $y = 2x + 6$,
If $x=0$, then $y=6$. Thus, the point is $(0,6)$.
If $y=0$, then $0 = 2x+6$, or $x=-3$. Thus, the point is $(-3,0)$.
Step 3: Graph the inequalities
Plot the points found in Steps 1 and 2 on the graph and draw a solid line for each since both are $\le$ or $\ge$. For the first inequality, shade the region above the line $y=-x+4$. For the second inequality, shade the region below the line $y=2x+6$.
Final Answer:
The solution is the region where the shadings overlap.
