The table shows the median home prices in Florida. What is the equation of a trend line that models a relationship between time and home prices? Use the equation to predict the median home price in 2020.

Year 1940 1950 1960 1970 1980 1990 2000
Median Price(\$) \$20,200 \$39,900 \$50,400 \$62,800 \$89,100 \$98,700 \$119,000

A. y = 1646.67x + 20,200; \$151,900

B. y = 49.4x + 20,200; \$119,000

C. y = 49.4x + 20,200; \$151,900

D. y = 1646.67x + 20,200; \$119,000

I chose D

• math -

since the price went up by roughly 100,000 in 60 years, that's an average annual increase of about 1650, so choice would be A or D.

Why did you pick D? The price was already 119,000 in 2000.
