This video tutorial covers graphing linear and quadratic equations. It begins with linear equations in slope-intercept form, explaining how to identify the slope and y-intercept, and how to plot them on a graph. The tutorial then moves to graphing equations in standard form by finding x and y-intercepts. It introduces quadratic functions, explaining transformations and how to graph them. The video concludes with advanced techniques for graphing quadratic functions, including factoring and finding the vertex and axis of symmetry.
