We have to write the linear equation.
Step-by-step explanation
Step 1.
The formula for the best-fitting line (or regression line) is 
, where m is the slope of the line and b is the y-intercept.
The formula for the slope, m, of the best-fitting line is 
where r is the correlation between x and y, and 
and 
are the standard deviations of the x-values and the y-values, respectively.
The formula for the y-intercept, b, of the best-fitting line is 
, where 
and 
are the means of the x-values and the y-values, respectively, and m is the slope.
