Slope and Rate of Change, Graphing Lines and Slope, Algebra Basics
Introducing slope as "a way of measuring the inclination of a line," Sal endeavors to provide a working knowledge of slope problems and problem-solving. The video is framed as a review but could be a good way to fill any holes in...
