Question Analysis
This question tests the student's ability to determine the constant rate of change from a graph by using two given points. The formula for the constant rate of change is provided, and students need to substitute the given coordinates into the formula.

Key Concept Explanation
The constant rate of change, or slope, is a measure of the steepness of a line. It is calculated as the ratio of the change in the y-coordinates to the change in the x-coordinates between any two points on the line.

Step-by-step Solution
1. Identify the coordinates of the two points: (2, 4) and (8, 10).
2. Apply the formula for the constant rate of change:
