Question Analysis
This question tests the student's ability to find the slope of a line using a table of values. The student must correctly identify the change in y and the change in x between two given points.

Key Concept Explanation
The slope of a line is calculated as the change in y divided by the change in x, or . This concept is fundamental in understanding the rate of change in linear relationships.

Step-by-step Solution
1. Identify the coordinates of the two points: (0, 8) and (4, 20).
2. Calculate the change in y:
