Final answer:
The slope of a line indicates its steepness and can be positive for an increasing line or negative for a decreasing line. Without a specific line or points provided, we cannot determine the exact slope.
Step-by-step explanation:
The question relates to the concept of slope in a linear equation. The slope of a line graphically represents how steep the line is, and algebraically it is defined as the change in y (vertical axis) over the change in x (horizontal axis). If the line has a positive slope, it means that as x increases, y also increases, hence it's an increasing line. Conversely, if the slope is negative, the line is a decreasing line, meaning as x increases, y decreases.
The given information implies that a comparison is being made between two lines, one which is an increasing line and one which is a decreasing line. To determine the slope of a specific line, one would typically use two points on the line to calculate the rise over run. However, without a specific line or points provided in the question, it is not possible to give an exact numerical answer to the student's question about the slope of 'the line shown below' as the line is not explicitly indicated in the text provided.
