The formula for the best fitting line is
[tex]y=mx+b[/tex]
Where m si the slope of the regression line and b is the y-intercept
Now at point
[tex]x=2021[/tex]
We shall get
[tex]y=615.769\times2021-(1.2045\times10^6)[/tex][tex]y=39969.149[/tex]
So number for 2021 can be predicted by the equation of the given line.
