The video tutorial explains how to graph linear equations using the slope-intercept form. It covers three examples: y = 2x - 1, y = 2/3x + 2, and y = -2x + 3. For each equation, the instructor demonstrates how to identify the slope and y-intercept, plot the y-intercept on the graph, and use the slope to find additional points. The tutorial emphasizes the importance of labeling the graph and using a ruler for accuracy.

Why is it important to label your graph with the equation?

• To ensure the instructor knows what graph is being represented

• To make it easier to draw

• To make the graph look complete

• To use up extra space
