Math Problem Statement

Analyze the system of inequalities represented by the graph, identifying slopes, y-intercepts, and inequalities for Line A and Line B.

Solution

Let’s analyze the graph and the inequalities step by step.

  1. Line A:

    • The slope of Line A is negative (downward slope). Using two points from the graph, the slope is 1-1 because it goes down 11 unit for every 11 unit to the right.
    • The yy-intercept of Line A is 33 (where the line crosses the yy-axis).
    • The shaded region below Line A indicates the inequality is yx+3y \leq -x + 3.
  2. Line B:

    • The slope of Line B is positive (upward slope). Using two points from the graph, the slope is 22 because it rises 22 units for every 11 unit to the right.
    • The yy-intercept of Line B is 4-4 (where the line crosses the yy-axis).
    • The shaded region above Line B indicates the inequality is y2x4y \geq 2x - 4.
  3. Shaded Region:

    • The shaded region is the overlapping solution area that satisfies both inequalities.

Final Inequalities:

  • Line A: yx+3y \leq -x + 3
  • Line B: y2x4y \geq 2x - 4

Tip:

Always test a point (e.g., (0,0)(0, 0)) to verify which side of the line satisfies the inequality.
