Solving for y in Slope-Intercept Form

The video tutorial explains how to convert equations into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. It provides step-by-step solutions for ten different equations, demonstrating how to isolate y and identify the slope and y-intercept. The tutorial also covers techniques for reducing fractions using a calculator.
