This lecture discusses the slope of lines including defining slope in terms of the angle of inclination and coordinates, as well as the slopes of parallel and perpendicular lines and the angle formed between two lines. It covers finding the slope of a line, how slope relates to the angle of a line, calculating slope using the rise over run formula with coordinates, determining if lines are parallel or perpendicular based on their slopes, and measuring the angle between two lines.
