Answers
x = year -1940
if x = 0 , y = 23,800
if x = 60, y = 113,100
slope = m = (113,100 - 23,800)/60
y = 1488.33 x +23,800
when year = 2040
x = 2040 - 1940 = 100 years
y = 1488.33 (100) + 23800
= 172,633
so the last one
if x = 0 , y = 23,800
if x = 60, y = 113,100
slope = m = (113,100 - 23,800)/60
y = 1488.33 x +23,800
when year = 2040
x = 2040 - 1940 = 100 years
y = 1488.33 (100) + 23800
= 172,633
so the last one
