Understanding Linear Functions through Graph Analysis

This video tutorial explains linear functions, focusing on the forms y = x and y = mx. It covers plotting points on a graph, understanding the concept of slope, and analyzing how different coefficients affect linearity. The video demonstrates that linear functions have a constant rate of change, regardless of the coefficient's value, whether positive, negative, or zero. It also highlights the importance of the slope, represented by the coefficient m, in determining the line's steepness and direction.

What happens to the graph of a linear function when the coefficient of x is changed?

How does changing the coefficient of x to a negative value affect the linear function?

What is the rate of change for the function y equals 0?
