Deriving the Equation Y = MX + B Using Similar Triangles

The video tutorial explains the derivation of the line equation y = mx + b using similar triangles. It begins by introducing the concept of slope as a constant ratio of rise over run. The tutorial then demonstrates how to derive the equation using a specific point and slope, and finally generalizes the derivation using variables. The key takeaway is understanding how similar triangles can be used to derive the line equation.
