The video tutorial explores the geometry of solutions for homogeneous and non-homogeneous equations in R2 with one free variable. It begins by solving the homogeneous equation, demonstrating that solutions are scalar multiples of a vector passing through the origin. The tutorial then addresses the non-homogeneous equation, showing that solutions form a line parallel to the homogeneous solutions but shifted by a constant vector. Graphical representations are used to illustrate these concepts, and the tutorial concludes with a summary of the findings.
