The correct inequality is \( v \leq -2x + 3 \).

Solución

To determine which inequality is represented by the graph, let's analyze the options provided: 1. **Boundary Line**: - If the graph uses a **solid line**, the inequality includes equality (i.e., ≤ or ≥). - If the graph uses a **dashed line**, the inequality does not include equality (i.e., < or >). 2. **Shading**: - **Shaded above the line** indicates the region where the inequality is **≥** or **>**. - **Shaded below the line** indicates the region where the inequality is **≤** or **<**. Given the options: - **a.) \( v \leq -2x + 3 \)** - **b.) \( v \geq -2x + 3 \)** - **c.) \( y < -2x + 3 \)** - **d.) \( v > -2x + 3 \)** Assuming the graph uses a **solid line** (indicating inclusion of equality) and the shading is **below** the line, the correct inequality would be: **a.) \( v \leq -2x + 3 \)** This represents all the points where \( v \) is less than or equal to \( -2x + 3 \), matching a solid boundary line with shading below. **Answer:** **a.) \( v \leq-2 x+3 \)**

To determine the correct inequality represented by the graph, it's key to analyze the line and its shading. If the graph shows a solid line with the area above the line shaded, it means that the inequality is of the type \( v \geq-2 x+3 \) or \( v >-2 x+3 \). Conversely, if it displays a dashed line with the area below the line shaded, the correct choices would be \( v \leq-2 x+3 \) or \( v < -2 x+3 \). Keep an eye out for the solid or dashed line—this will lead you toward the correct inequality form! Understanding how to interpret these visual cues is crucial for accurately judging such situations and making sense of graphical data. For example, when lines are dashed, it indicates that points on the line are not included in the solution, aligning with "less than" or "greater than" inequalities. Solid lines tackle situations where the boundary is included, leading to "less than or equal to" or "greater than or equal to." This key insight can steer you toward making better graphical interpretations and conclusions in your math journey!
