1. The problem is to match the graph with the correct slope type: positive, zero, undefined, or negative. 2. Recall the definitions of slope: - Positive slope: line rises from left to right. - Zero slope: horizontal line. - Undefined slope: vertical line. - Negative slope: line falls from left to right. 3. Given the graphs: - Top graph: line going downward from left to right, so slope is negative. - Second graph: horizontal line, so slope is zero. - Third graph: vertical line, so slope is undefined. - Bottom graph: line going upward from left to right, so slope is positive. 4. Therefore, the matching is: - Top graph: negative slope. - Second graph: zero slope. - Third graph: undefined slope. - Bottom graph: positive slope.
