Student Population Growth and Change

The video tutorial explains how to model student population changes in a school using linear equations. It starts with an initial population of 520 students in 2005 and explores different scenarios of population changes over the years. The tutorial covers how to write equations in slope-intercept form, calculate the slope as the rate of change, and simplify rates. Examples include both increases and decreases in population, as well as constant population scenarios. The video also explains how to handle semester-based changes by converting rates appropriately.

How does the equation change when the student population remains constant?

• n = 520 - 7t

• n = 520

• n = 520 + 20t

• n = 520 + 10t
