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

Answer 1

x = 0 for 1940 as
y = 0 + 20,200 for 1940
for 1950, x = 10
y = 36666 which is close to given price

looks like A is the closest equation

for 2020

y = 1646.67*80 + 20,200 = 151933
