Graphing a linear equation in slope intercept form

The video tutorial explains how to identify and graph a horizontal line in slope-intercept form. It begins by discussing the Y-intercept and the absence of an X term, leading to a slope of zero. The tutorial then demonstrates how to graph this equation by plotting the Y-intercept and drawing a horizontal line through it.

Describe how to graph the Y intercept at (0, -4).

Explain the significance of creating a horizontal line in slope intercept form.
