Which system is the solution of the graph?

Solution

From the graph you provided, we see two linear inequalities:

  1. The line with a negative slope appears to be y=x+2y = -x + 2, and the shading is to the left (below) of this line, suggesting that the inequality is yx+2y \leq -x + 2.
  2. The line with a positive slope appears to be y=x2y = x - 2, and the shading is above this line, suggesting that the inequality is yx2y \geq x - 2.

This system corresponds to the third option:

\begin{aligned} y & \leq -x + 2 \\ y & \geq x - 2 \end{aligned} \right.$$ Would you like more details or have any questions? Here are 5 related questions to consider: 1. How do you graph a linear inequality like $$y \geq x - 2$$? 2. What is the significance of the shaded region in a system of inequalities? 3. How can you check if a point is a solution to a system of inequalities? 4. What changes if the inequalities are strict (e.g., $$y < x - 2$$) instead of inclusive (e.g., $$y \leq x - 2$$)? 5. How does the solution of a system of inequalities relate to the intersection of regions? **Tip:** Always test a point from the shaded region to verify that it satisfies the system of inequalities.
