A study was done to see the relationship between the time it takes, 𝑥, to complete a college degree and the student loan debt incurred, 𝑦. The equation of the regression line was found to be 𝑦=25142+14329𝑥.
According to the model, how much student loan debt would someone have if they completed a degree in 4 years?
$82,458
