Graphing Linear Equations: Slope and Intercepts

The video tutorial explains how to identify the slope and intercepts of a linear equation in slope-intercept form. It demonstrates how to find the vertical and horizontal intercepts both algebraically and graphically. The tutorial also covers how to use the slope to plot additional points and accurately graph the line, verifying the intercepts in the process.
