Finding Slope from a Graph

This video tutorial introduces Algebra Strats, a class designed to provide extra practice and content review to prepare students for Algebra One. The focus of this week's lessons is on understanding and calculating slopes, also known as the rate of change. The video explains the four types of slopes: positive, negative, undefined, and zero. It provides guidance on calculating slopes from graphs, including simplifying fractions. The tutorial includes practice problems to reinforce the concepts taught, with an emphasis on using visual aids and step-by-step instructions.
