Create Equations for Linear Models Using Tables

This video tutorial explains how to create and understand linear relationships using slope-intercept form. It covers the basics of linear growth, how to write linear functions, and graphing them. The tutorial uses practical examples, such as calculating the weight of a backpack with books, to illustrate these concepts. It also addresses common mistakes, like confusing slope with intercept, and explains the difference between continuous and discrete variables.

If a backpack weighs 3 pounds with no books, and each book weighs 1.5 pounds, what is the equation representing the total weight?

What does it mean if the slope of a linear equation is negative?
