Understanding Linear Models: Parts and Meanings

This video tutorial explains the components of a linear model, focusing on the equation y = mx + b. It covers the coordinate plane, the meaning of x and y values, and the significance of the slope (m) and y-intercept (b). Different types of slopes—positive, negative, zero, and undefined—are discussed, along with how they affect the line's direction. The tutorial also explains how the y-intercept is the point where the line crosses the y-axis.

How can you identify the coordinates of a point on the coordinate plane?

What does it mean if a linear model has an undefined slope?
