The slope or rate of change in the scenario can be calculated by finding the difference in the average price of a home between the two given years and then dividing it by the number of years.
Slope or rate of change = (Change in average price of a home)/(Change in years)
Slope = ($109,000 - $97,000)/(1986 - 1980)
Slope = $12,000/6
Slope = $2,000 per year
The slope of $2,000 per year means that, on average, the price of a home in Brainerd County increased by $2,000 each year between 1980 and 1986.
In 1980 the average price of a home in Brainerd County was $97,000. By 1986 the average price of a home was $109,000.
