Solving for y: A Comprehensive Guide

The video tutorial explains how to find the slope and y-intercept from a linear equation by solving for y to achieve the y = mx + b format. It introduces the solving square method, demonstrates distributing and grouping terms, and provides two example problems to illustrate the process. The tutorial emphasizes isolating y and identifying the slope and y-intercept from the equation.
