The video tutorial explains how matrix multiplication can be used to transform objects on a coordinate plane. It begins with an introduction to matrix multiplication and its application in transformations. The tutorial then details the setup of matrices and the conditions for a defined product. A step-by-step calculation of the matrix product is demonstrated, followed by plotting the new points to analyze the transformation. The video concludes with a discussion on the applications of matrix multiplication in performing various transformations.
