Solving Slope-Intercept Form Word Problems

This video tutorial from Education Lifeline teaches how to solve word problems using the slope-intercept form. It begins with an introduction to the concept and explains how to identify the slope (M) and y-intercept (B) from a word problem. The tutorial then demonstrates how to calculate the total cost of a gym membership after four months and how to determine the number of months for a given total cost. The video concludes with a call to action for viewers to like, subscribe, and explore additional resources.
