The video tutorial covers graphing proportions, rates, and slope. It explains how to represent proportional relationships in tables, graphs, and equations. The tutorial highlights the constant of proportionality, slope, and unit rate, showing how they interrelate. Key observations include the straight-line nature of proportional graphs, their passage through the origin, and how the slope's steepness is determined by the constant of proportionality.
