Master Writing the direct variation equation of a line through a given point

The video tutorial explains how to write an equation in direct variation form that passes through a given point. It covers the relationship between direct variation and the slope-intercept form, emphasizing that the y-intercept in direct variation is zero. The tutorial demonstrates graphing to find the slope and provides alternative methods using the slope formula. It also discusses simplifying the process by using the ratio of y to x to determine the slope.
