The regression equation is given by [tex]\overline{y}=50-0.01x[/tex]
We have given that,
The scatter plot shows the relationship between the mass of a tree and the total mass of the vegetation within 100 square meters of the tree.
The slope =change in y/change in x
We have given the two points (100,40) and (25000,2)
Therefore the slope of the given point is,
[tex]=\frac{25-40}{2500-1000} \\=-0.01[/tex]
The y-intercept is the value of y when x=0 this implies that y=50
Therefore the regression equation is given by
[tex]\overline{y}=50-0.01x[/tex]
