The video tutorial explains how to find X and Y intercepts in equations. It begins with an introduction to X intercepts, followed by a detailed explanation of solving for X when it appears in the denominator. The instructor demonstrates how to write intercepts as coordinate points and introduces a shortcut for finding X intercepts by setting the numerator to zero. The tutorial also covers finding Y intercepts by setting X to zero and concludes with a note on the absence of slant asymptotes.
