Answer
Answers may vary.
One formula found to fit the data was $y=97x+1294$.
Work Step by Step
Two data points were used to determine the slope of the line of best fit (and then used to determine the line of best fit).
$(2, 1488)$
$(4, 1682)$
$y=mx+b$
$m=(1682-1488)/(4-2)$
$m=194/2$
$m=97$
$y=mx+b$
$y=97x+b$
$(2,1488)$
$y=97x+b$
$1488=97*2+b$
$1488=194+b$
$1488-194=194+b-194$
$1294=b$
$y=97x+1294$
