Question

The decline of salmon fisheries along the Columbia River in Oregon has caused great concern among commercial and recreational fishermen. The paper 'Feeding of Predaceous Fishes on Out-Migrating Juvenile Salmonids in John Day Reservoir, Columbia River' (Trans. Amer. Fisheries Soc. (1991: 405-420) gave the accompanying data on y = maximum size of salmonids consumed by a northern squaw fish (the most abundant salmonid predator) and x = squawfish length, both in mm. Here is the computer software printout of the summary:

Coefficients:                  
      Estimate     Std. Error     t value     Pr(> |t|)  
(Intercept)   −89.010     16.703     −5.329     0.000  
Length   0.705     0.046     15.293     0.000  


Using this information, give the equation of the least squares regression line.
