A line passes through the points $$(7, 8)$$ and $$(11, 8)$$ ...

Question Analysis
This question evaluates the student's ability to determine the slope of a line when the y-coordinates of the points are identical. The slope of a horizontal line is 0.

Key Concept Explanation
The key concept here is that if the y-coordinates of two points are the same, the line is horizontal, and the slope is 0.

Step-by-step Solution
1. Use the slope formula:
