Math Problem Statement
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:
-
Identify the Lines:
- One line has a negative slope and a y-intercept of +3. It could be represented as .
- The other line has a slope of +1 and a y-intercept of -3, likely represented as .
-
Determine the Inequalities:
- The shading above or below each line tells us if it's "greater than" or "less than":
- For the line , the shading appears above it, indicating .
- For the line , the shading appears above it as well, indicating .
- The shading above or below each line tells us if it's "greater than" or "less than":
-
Combine the Inequalities:
- The final inequalities describing the shaded region should be:
- The final inequalities describing the shaded region should be:
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:
- What is the general method for graphing inequalities on a coordinate plane?
- How do you determine whether to shade above or below a line for inequalities?
- How can you verify solutions that fall within the shaded region of an inequality graph?
- What are the differences between strict inequalities (>) and non-strict inequalities (≥)?
- 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).
