A management company opens a large apartment complex in anticipation of growth in the community. The company compiles statistics
and trends every two weeks to share with potential residents of the apartment complex. The graph shows the line of best fit for data collected on the number of apartments available in the complex as a function of the number of weeks since the complex has been open. The equation of the line of best fit for this situation is given below.

The equation is given to us in slope intercept form. -34.85 is the slope and the y-intercept is 938.
Therefore, we can say: The rate of change for the line of best fit is -34.85 which represents the decrease in number of available apartments per week since the complex opened. The y-intercept is 938 which represents the number of apartments when it first opened.
