This video tutorial introduces linear equations and their standard form, AX + BY = C, where A, B, and C are real numbers. It explains how to identify linear equations and differentiate them from non-linear ones. The video focuses on finding x and y-intercepts of equations, demonstrating the process with examples. It covers graphing linear equations using intercepts and also touches on graphing non-linear equations, highlighting the differences. The tutorial aims to help viewers understand intercepts and graph equations effectively.

Which of the following is a characteristic of a linear equation in standard form?
