The video tutorial explains how to determine the rate of increase for a linear function f by examining its table of values. It demonstrates how to calculate the rate of change as 7/4 and visually verify this by plotting points. The tutorial then compares different graphs to identify which one has the same slope as f, concluding that graph D matches. The process of verification is also shown, ensuring that the slope of graph D is consistent with the calculated rate of change.
