Math Problem Statement

Write the inequalities based on the shaded region shown on the graph.

Solution

The image shows a question asking to identify the inequalities represented by a shaded region on a coordinate plane, with given options. The graph in the image includes two linear boundaries and a shaded region that corresponds to the solution set of these inequalities.

To determine the correct inequalities, let's analyze the graph:

  1. Identify the Lines:

    • One line has a negative slope and a y-intercept of +3. It could be represented as y=2x+3y = -2x + 3.
    • The other line has a slope of +1 and a y-intercept of -3, likely represented as y=x3y = x - 3.
  2. Determine the Inequalities:

    • The shading above or below each line tells us if it's "greater than" or "less than":
      • For the line y=2x+3y = -2x + 3, the shading appears above it, indicating y2x+3y \geq -2x + 3.
      • For the line y=x3y = x - 3, the shading appears above it as well, indicating yx3y \geq x - 3.
  3. Combine the Inequalities:

    • The final inequalities describing the shaded region should be:
      • y2x+3y \geq -2x + 3
      • yx3y \geq x - 3

From the options visible in the image, the correct choice would be the second option (y > -2x + 3, y ≥ x - 3), provided that this choice is interpreted correctly based on the graph.

Would you like more details or have any questions? Here are some related questions:

  1. What is the general method for graphing inequalities on a coordinate plane?
  2. How do you determine whether to shade above or below a line for inequalities?
  3. How can you verify solutions that fall within the shaded region of an inequality graph?
  4. What are the differences between strict inequalities (>) and non-strict inequalities (≥)?
  5. How do boundary lines affect the solution sets of systems of inequalities?

Tip: When interpreting graph shading, remember that "≥" or "≤" means the line itself is part of the solution (solid line), while ">" or "<" means the solution does not include the line (dashed line).
