Exploring the Line Equation: Slope and Y-Intercept

The video tutorial covers the basics of line equations, focusing on the y-intercept. It explains the components of the line equation y = mx + b, including how to identify and solve for the y-intercept. The tutorial provides a step-by-step example problem and concludes with practice instructions for students.
