Exploring Linear Equations and Their Forms

This video tutorial reviews linear equations, covering their forms: slope-intercept, standard, and point-slope. It explains how to calculate slope using rise over run, and identifies x and y intercepts. The video also discusses parallel and perpendicular lines, and demonstrates graphing techniques for linear equations. Practice problems are included to reinforce learning.
