Exploring Slope Calculations from Tabular Data

This video tutorial explains how to calculate the slope of a line using an XY table. It covers the concept of slope as the ratio of the difference in consecutive Y values to the difference in consecutive X values. The tutorial includes multiple examples, demonstrating how to find the slope in different scenarios, including when using function notation like f(x) and g(x). It also addresses special cases such as vertical and horizontal lines. The video concludes with practice problems for viewers to solve independently.
