Math Problem Statement

Which system of inequalities is represented by the graph?

Solution

To determine the correct system of inequalities represented by the graph, let's analyze the format and reasoning for each choice in the options provided. We need to interpret each inequality’s slope, y-intercept, and orientation (greater than, less than, or equal) as well as their intersections to determine which could match a given graph:

  1. Understanding each inequality's meaning:

    • Inequalities like y<2x2y < -2x - 2 or y>2x2y > -2x - 2 have a slope of -2 and a y-intercept of -2.
    • Inequalities with y12x+6y \leq -\frac{1}{2}x + 6 or similar have a slope of 12-\frac{1}{2} and a y-intercept of 6.
    • Inequalities with yxy \leq x or yxy \geq x have a slope of 1 and a y-intercept of 0.
  2. Checking each answer choice:

    • Option A: Contains inequalities:
      • y>2x2y > -2x - 2 (region above the line y=2x2y = -2x - 2)
      • y12x+6y \leq -\frac{1}{2}x + 6 (region below the line y=12x+6y = -\frac{1}{2}x + 6)
      • yxy \leq x (region below the line y=xy = x)
    • Option B: Similar structure but with y<2x2y < -2x - 2, y12x+6y \leq -\frac{1}{2}x + 6, and yxy \geq x.
    • Option C and D: Follow similar patterns but with different inequalities and combinations.
  3. Selecting the answer:

    • If the graph shows a shaded region, match the areas that satisfy all inequalities simultaneously. You would look for overlapping shaded regions from each line in the system.

Would you like me to continue with a detailed evaluation of each option’s suitability based on the graph's characteristics?
