Algebra-1

To determine whether the relationship described by the graph is proportional, linear, and positive or negative, let's analyze it step by step:

1. Proportional or Non-Proportional: To determine if the relationship is proportional, we check if all data points lie on a straight line that passes through the origin (0,0). In this case, the graph does not pass through the origin (0,0), then the relationship described by the points is not proportional.

2. Linear: A relationship is linear if the points lie on a straight line. Visually, if the points form a straight line when plotted on a graph, the relationship is linear. The graph do indeed form a straight line when plotted, indicating a linear relationship.

3. Positive or Negative: Determine the slope to check if it's positive or negative:...
