Math Problem Statement

Identify the system of inequalities from the graph.

Solution

In the image you provided, the shaded region represents the solution to a system of linear inequalities. I will determine the inequalities based on the graph.

Steps to identify the inequalities:

  1. Identify the boundary lines:

    • There are two boundary lines, one vertical and one slanted.
    • The slanted line has a negative slope and intersects the y-axis above the origin.
    • The vertical line appears to be located at x=1x = 1.
  2. Determine the equations of the lines:

    • The vertical line is straightforward: it is x=1x = 1.
    • The slanted line appears to pass through points like (0,3)(0, 3) and (3,0)(3, 0). This gives a slope of 1-1, so its equation is y=x+3y = -x + 3.
  3. Determine the inequality signs:

    • The shading on the left side of x=1x = 1 means the inequality for this boundary is x1x \leq 1.
    • The shading above the slanted line suggests the inequality is yx+3y \geq -x + 3 because the shading is above the line.

Final System of Inequalities:

  1. x1x \leq 1
  2. yx+3y \geq -x + 3

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

  1. How do we graph inequalities like these manually?
  2. How can we verify if a point is a solution to this system?
  3. What changes if the inequality were strict, like x<1x < 1?
  4. Can inequalities have different boundary types (e.g., dashed lines)?
  5. How do we interpret systems with more than two inequalities?

Tip: Always test a point (like the origin) when determining the correct region to shade for an inequality.
