The video tutorial explains how to determine a linear equation representing the cost of tuition as a function of the number of years since 1995. It starts by discussing tuition costs in 1995 and 2005, then introduces function notation and ordered pairs. The tutorial guides viewers through calculating the linear function, determining the slope and intercept, and finalizing the linear equation.
