Math Problem Statement

Which of the following systems of inequalities would produce the region indicated on the graph?

Solution

Looking at the graph provided, we can observe that the shaded region is bounded by two lines and specific constraints:

  1. Line 1 (y ≥ x + 1): This line has a slope of 1 and y-intercept at (0, 1), which forms the boundary of the shaded region on the left side. The shading is above this line, so the inequality would be yx+1y \geq x + 1.

  2. Line 2 (y ≤ 10): This is the horizontal line at y=10y = 10 that forms the top boundary of the shaded region. The region is below this line, so the inequality would be y10y \leq 10.

  3. Constraint on x (x ≥ 0): The graph shows that the region is limited to the right of the y-axis, meaning x0x \geq 0.

Therefore, the correct system of inequalities is:

  • yx+1y \geq x + 1
  • y10y \leq 10
  • x0x \geq 0

This matches Option C.

Final Answer: C. yx+1;y10;x0y \geq x + 1; y \leq 10; x \geq 0

Here are 5 related questions to expand on this:

  1. How do you determine if a region is above or below a line in inequalities?
  2. What does the inequality x0x \geq 0 represent in a graph?
  3. How do boundary lines affect shading in inequalities?
  4. Can a region be bounded by curves instead of straight lines? How would that change the inequalities?
  5. How do you interpret a system of inequalities geometrically?

Tip: When graphing inequalities, use test points (like (0,0)(0,0)) to check which side of the boundary should be shaded!
