When is the particle at rest from a velocity graph

The video tutorial explains how to determine when a function is at rest by analyzing its velocity graph. It covers finding the slope of a line using given points and deriving the equation of a line in slope-intercept form. The tutorial also demonstrates how to find the x-intercept by setting y to zero, providing a comprehensive understanding of these mathematical concepts.
