The video tutorial explains how to find the tangent line to a given function and determine the instantaneous rate of change, or slope, of that tangent line. It begins with an introduction to the problem, followed by steps to find the derivative using the power rule. The tutorial includes a correction of a calculation error and demonstrates the application of the power rule to find the derivative. Finally, it shows how to calculate the slope of the tangent line at a specific point.
