Explanation:

Identify boundary line properties

The visible graphs show a boundary line passing through specific grid intersections. Let's determine the equation of this boundary line.
Looking closely at the second graph (which is highlighted):

  • The \(y\)-intercept is at \((0, 2)\).
  • Another clear point on the line is \((1, -1)\) or \((2, -4)\).
  • Let's calculate the slope \(m\):
$$ m = \frac{-1 - 2}{1 - 0} = -3 $$
  • Thus, the equation of the boundary line is:
$$ y = -3x + 2 $$

Analyze inequality representations

In linear inequality graphing:

  • A dashed boundary line represents a strict inequality (\(<\) or \(>\)).
  • A solid boundary line represents a non-strict inequality (\(\le\) or \(\ge\)).
  • The top graph shows a dashed boundary line:
$$ y < -3x + 2 \quad \text{or} \quad y > -3x + 2 $$
  • The bottom graph shows a solid boundary line:
$$ y \le -3x + 2 \quad \text{or} \quad y \ge -3x + 2 $$

Determine shaded regions

Let's analyze the shaded region for the selected bottom graph:

  • The shaded region lies to the left/below the solid line.
  • Let's test the origin \((0,0)\), which is in the shaded region:
$$ 0 \le -3(0) + 2 \implies 0 \le 2 \quad (\text{True}) $$
  • Therefore, the bottom graph represents the inequality:
$$ y \le -3x + 2 $$
  • The top graph has a dashed line with the same shaded region, representing:
$$ y < -3x + 2 $$

Answer:

The highlighted bottom graph represents the linear inequality with a solid boundary line:

  • The graph of \(y \le -3x + 2\) (solid boundary line with shading below/left) (Correct answer)
  • The graph of \(y < -3x + 2\) (dashed boundary line with shading below/left)
