The video tutorial demonstrates two methods to rewrite equations into slope-intercept form. The first method involves eliminating fractions by multiplying through, while the second method uses reciprocals. Both methods lead to the same result, allowing the identification of the slope and y-intercept. The tutorial concludes by summarizing the process and identifying the slope as 4/3 and the y-intercept as -20.
