maybe it'd be easier without all the zeros:
1 18
2 37
3 48
4 66
y=17x comes close. The errors are
1 +1
2 +3
3 +1
4 -2
Use your favorite regression tool for a more exact line. The best-fit line is
y = 15.5x + 3.5
a good calculator and grapher is at
http://www.alcula.com/calculators/statistics/linear-regression/
It requires at least 5 data points, though so enter 5,81 as a 5th point, since it is exactly on the line of best fit.
(100, 18,000)
(200, 37,000)
(300, 48,000)
(400, 66,000)
Write an equation for the line that models the data.
